FATFS enable support for multiple drives
Current implementation has drive numbers and paths hardcoded to support
only one FATFS drive. Arduino has it's own SPI driver to allow
compatibility and flexibility. With the MR it is possible to have up to
```_VOLUMES``` drives connected (SPI, SDMMC and others) at the same
time and accessed through VFS

lwip: modify dhcp timer granularity from 60s to 1s
Current DHCP granularity is 60 seconds, it's not accurate, it can cause DHCP release/rebind/renew timer
timeout at the same time, also it may renew/rebind/release at wrong time, thus cause problem.

Fix a scheduling bug
Fixes:
- Trivial bug where in some special cases a task could be started on the wrong core (and would run there for max 1 tick)
- More major bug causing a yield to be done with a mux held.

Fix SPI master transmit length
Tx/Rx length fix from https://github.com/espressif/esp-idf/pull/336
I also added an extra commit in to make use of a define instead of a literal, plus fix a (harmless) off-by-one condition.
See merge request !521
This fixes incorrect descriptions of I_END/I_SLEEP instructions and
changes the definition of I_END. New instruction, I_WAKE, is added,
which wakes up the SoC. Macro for ADC instruction is defined, and new
tests are added.
This change adds esp_deep_sleep_get_wakeup_cause, which returns the
source which has caused wakeup from deep sleep.
Similar to esp_deep_sleep_get_ext1_wakeup_status, a function is added
to check touch pad wakeup status: esp_deep_sleep_get_touchpad_wakeup_status.
This function returns the touch pad which has caused wakeup.
ULP and touch FSMs in ESP32 revisions 0 and 1 do not operate correctly
if RTC_PERIPH power domain is force powered on (ESP_PD_OPTION_ON).
Both ULP and touch still work, but clock frequency of the ULP may be
incorrect and touch values may be off by considerable amount. As such,
when these wakeup modes are used, RTC_PERIPH power domain has to be set
to ESP_PD_OPTION_AUTO (or, in the current implementation,
ESP_PD_OPTION_OFF — though this will change in the future when _OFF will
actually *force* the power domain to be powered off).
Because EXT0 wakeup source requires RTC_PERIPH to be powered ON, mark
ULP and touch wakeup sources as incompatible with EXT0. Workaround for
this is to use EXT1 wakeup source instead, which offers similar or
better functions without having to keep RTC_PERIPH powered on.
- I_RD_REG used the wrong union member (.rd_reg) due to a copy-paste
mistake
- Peripheral register address in bits[7:0] should be given in words,
not in bytes

Deep sleep fixes
This change fixes extra 24 uA current consumption in deep sleep mode (https://esp32.com/viewtopic.php?f=2&t=1133).
Recent update to libphy/librtc caused another problem that WiFi related parts of RTC are no longer disabled by RTC sleep functions. This means that if WiFi is not disabled by the application before entering deep sleep, extra ~200uA of current would be consumed. This is fixed, and documentation for esp_deep_sleep and SNTP example are updated to mention that applications should take care of disabling WiFi and BT before going into the deep sleep mode.

spi_flash: fix protection issues
This MR fixes the two spi_flash related issues:
- esp_intr_noniram_{disable,enable} not being protected by spi_flash_op_{lock,unlock} in single core mode. This caused a safety assert to be triggered in esp_intr_noniram_disable.
- spi_flash_unlock not being protected by spi_flash_guard_{start,end}. This caused a conflict between SPI0 and SPI1 controllers when accessing SPI flash, manifesting in cache data corruption and IllegalInstruction exceptions, for some flash chips.
See merge request !522
spi_flash_unlock was missing spi_flash_guard_start, which caused cache
to be enabled during unlock operation, causing hard-to-trace crashes
and cache data corruption.
MR !441 (7c155ab) has fixed issue with esp_intr_noniram_{disable,enable}
calls not being properly protected by spi_flash_op_{lock,unlock}.
Unit test was added, but the unit test environment tests only dual-core
config. Similar issue was present in the code path for the single-core
config, where esp_intr_noniram_{disable,enable} calls were unprotected.
This change fixes the protection issue and updates the unit test to
run properly in single core config as well.
The issue with running unit tests for single core config will be
addressed in a separate MR.
In case WiFi/BT stack has been enabled but wasn’t disabled, some RTC
bits may be left enabled, causing increased current consumption.
This change returns some of the bits back to their default values.
Bootloader enables SAR ADC in test mode to get some entropy for the RNG.
The bits which control the ADC test mux were not disabled, which caused
extra ~24uA current to be drawn from VRTC, increasing deep sleep current
consumption. This change disables relevant test mode bits in
bootloader_random_disable.
1. add new APIs bt controller enable/disab/deinit
2. make bt controller work need to call two APIs of esp_bt_controller_init and enable
3. modify phy init to make mac reset once
1. add a macro in menuconfig for users to choose whether store phy calibration data into NVS or not.
2. rename some disable phy and rf APIs so that existing code which calls old APIS will fail to compile.
1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API).
2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API).
3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done.
4. Add an function to get OS tick rate.
5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0.
This connection error caused by iPhone, it think that TX data length must large than 27 when slave support EXTEND_DATA_LENGTH. But this should be allow. Besides, the problem cannot be found on higher version of Iphone7, apple seemed to have fixed it.
Actually maybe other BLE device have the same problem.

phy_init: don’t rewrite valid calibration data
In the default PHY init routine, calibration data is loaded from NVS.
Most of the time the incremental changes to calibration will be fairly
small, so we don’t need to rewrite the existing calibration data stored
in the NVS.
Possible enhancement to be done in the future: expose a function in PHY
library to tell how big was the change in calibration data. If the
change was significant, then calibration data stored in NVS should be
updated.

freertos: fix protection issue in freertos queue event list
When functions in queue.c calls listLIST_IS_EMPTY() to check queue event list, the queue list is
protected by queue mutex, on the other hand, when xTaskIncrementTick() modify the queue list, the
queue list is protected by xTaskQueueMutex, this may cause xTaskRemoveFromEventList operate on
the empty queue list and cause problem.
This change works around the problem by reducing the window where the race condition can happen.
See merge request !465
Also add steps to disable flash encryption, as some people seem to
accidentally enable it.
Explicitly mark the flash encryption and secure boot as "READ DOCS
FIRST" in menuconfig.

Fix interrupting task on other CPU that has lower prio than current task on current CPU
Fix for a very subtle bug introduced somewhere in december. This bug would cause a cross-core interrupt to only be sent if the activated task has a higher priority than the task currently running on *this* cpu, instead of on the other CPU.

Add missing variable initialisation to make SPI work for multiple CS
Ref https://github.com/espressif/esp-idf/pull/277
From PR: "I am not especially familiar with this platform or with esp-idf -- so review with care.
The spi-master driver would not work for me when the number of devices on a bus exceeded 1 (caused device hang). I believe this is because cur_cs is not properly set (anywhere), and yet is used. This is likely just not noticed because 0 is presumably the correct value when there's only 1 device (and I'm guessing multi-device setup is not tested as thoroughly).
Simply setting cur_cs to the correct slot value resolves the problem and multiple devices on a single bus behave correctly in my test environment."
Looks like a small oversight on my side.
