afef16c2e9 spi_flash: Support suspend/resume mode for operations
- Adds arbitration between the erase and write in suspend mode
     (If the flash memory is suspended then only a read operation can be performed.)
- espcoredump: Dump does not use suspend feature, just resume before continue.
- spi_flash: Add release_cpu() to do suspend/release_cpu/resume

fefdee1349 bootloader: fix the WRSR format for ISSI flash chips
1. The 2nd bootloader always call `rom_spiflash_unlock()`, but never help to clear the WEL bit when exit. This may cause system unstability.

   This commit helps to clear WEL when flash configuration is done.

   **RISK:** When the app starts, it didn't have to clear the WEL before it actually write/erase. But now the very first write/erase operation should be done after a WEL clear. Though the risk is little (all the following write/erase also need to clear the WEL), we still have to test this carefully, especially for those functions used by the OTA.

2. The `rom_spiflash_unlock()` function in the patch of ESP32 may (1) trigger the QPI, (2) clear the QE or (3) fail to unlock the ISSI chips.

   Status register bitmap of ISSI chip and GD chip:

| SR | ISSI | GD25LQ32C |
| -- | ---- | --------- |
| 0  | WIP  | WIP       |
| 1  | WEL  | WEL       |
| 2  | BP0  | BP0       |
| 3  | BP1  | BP1       |
| 4  | BP2  | BP2       |
| 5  | BP3  | BP3       |
| 6  | QE   | BP4       |
| 7  | SRWD | SRP0      |
| 8  |      | SRP1      |
| 9  |      | QE        |
| 10 |      | SUS2      |
| 11 |      | LB1       |
| 12 |      | LB2       |
| 13 |      | LB3       |
| 14 |      | CMP       |
| 15 |      | SUS1      |

   QE bit of other chips are at the bit 9 of the status register (i.e. bit 1 of SR2), which should be read by RDSR2 command.

   However, the RDSR2 (35H, Read Status 2) command for chip of other vendors happens to be the QIOEN (Enter QPI mode) command of ISSI chips. When the `rom_spiflash_unlock()` function trys to read SR2, it may trigger the QPI of ISSI chips.

   Moreover, when `rom_spiflash_unlock()` try to clear the BP4 bit in the status register, QE (bit 6) of ISSI chip may be cleared by accident. Or if the ISSI chip doesn't accept WRSR command with argument of two bytes (since it only have status register of one byte), it may fail to clear the other protect bits (BP0~BP3) as expected.

   This commit makes the `rom_spiflash_unlock()` check whether the vendor is issi. if so, `rom_spiflash_unlock()` only send RDSR to read the status register, send WRSR with only 1 byte argument, and also avoid clearing the QE bit (bit 6).

3. `rom_spiflash_unlock()` always send WRSR command to clear protection bits even when there is no protection bit active. And the execution of clearing status registers, which takes about 700us, will also happen even when there's no bits cleared.

   This commit skips the clearing of status register if there is no protection bits active.

Also move the execute_flash_command to be a bootloader API; move
implementation of spi_flash_wrap_set to the bootloader

37423083bb spi_flash: add config option to override flash size in bootloader header
Sometimes the flash size read from bootloader is not correct. This may
forbid SPI Flash driver from reading the the area larger than the size
in bootloader header.

When the new config option is enabled, the latest configured
ESPTOOLPY_FLAHSIZE in the app header will be used to override the value
read from bootloader header.

05da91f0db spi_flash: add configuration option to select flash write chunk size
Flash write operation is broken down into smaller chunk writes. Size
of this chunk was previously set to 8K but that in-turn meant cache and
non-IRAM resident interrupts could stay disabled upto ~24msec for 8K flash
write operation. If chunk size is brought down to 256 (typical flash page size)
then it brings down cache and non-IRAM interrupts disable duration to ~1msec.

Fix here keeps defaults same but provides configuration option to tweak the
setting based on application requirement.

fdf983e0c4 spi: fix config break and reduce overhead of the bus lock on SPI1
The SPI bus lock on SPI1 introduces two side effects:

1. The device lock for the main flash requires the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` to be selected, however this
option is disabled by default in earlier IDF versions. Some developers
may find their project cannot be built by their old sdkconfig files.

2. Usually we don't need the lock on the SPI1 bus, due to it's
restrictions. However the overhead still exists in this case, the IRAM
cost for static version of semaphore functions, and the time cost when
getting and releasing the lock.

This commit:

1. Add a CONFIG_SPI_FLASH_BYPASS_MAIN_LOCK option, which will forbid the
space cost, as well as the initialization of the main bus lock.

2. When the option is not selected, the bus lock is used, the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` will be selected explicitly.

3. Revert default value of `CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION`
to `n`.

introduced in 49a48644e4.

3b429766bc esp_flash: support MXIC flash chips
The default chip driver (chip_generic) use command 01H + 2 bytes to
clear the QE bit. However this will accidently change the configuration
register value of the MXIC chip.

MXIC chip driver is added to fix that.
