cd79f3907d gpio: Disable USB JTAG when setting pins 18 and 19 as GPIOs on ESP32C3
When `DIS_USB_JTAG` eFuse is NOT burned (`False`), it is not possible
to set pins 18 and 19 as GPIOs. This commit solves this by manually
disabling USB JTAG when using pins 18 or 19.
The functions shall use `gpio_hal_iomux_func_sel` instead of
`PIN_FUNC_SELELECT`.

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.

9d9d22c920 esp_flash: deprecate the cs_id member, which is no longer used.
We used to manually specify the CS id. However after the SPI bus lock is
introduced, the lock is responsible to assign the CS lines and provide
the CS id. The esp_flash driver now depends on the ID assigned by the
SPI bus lock, the configuration field is deprecated.

571864e8ae esp_flash: fix set qe bit and write command issues
There used to be dummy phase before out phase in common command
transactions. This corrupts the data.

The code before never actually operate (clear) the QE bit, once it finds
the QE bit is set. It's hard to check whether the QE set/disable
functions work well.

This commit:

1. Cancel the dummy phase

2. Set and clear the QE bit according to chip settings, allowing tests
   for QE bits. However for some chips (Winbond for example), it's not
   forced to clear the QE bit if not able to.

3. Also refactor to allow chip_generic and other chips to share the same
   code to read and write qe bit; let common command and read command share
   configure_host_io_mode.

4. Rename read mode to io mode since maybe we will write data with quad
   mode one day.

511820820e esp_flash: fix the coredump issue
During coredump, dangerous-area-checking should be disabled, and cache
disabling should be replaced by a safer version.

Dangerous-area-checking used to be in the HAL, but it seems to be more
fit to os functions. So it's moved to os functions. Interfaces are
provided to switch between os functions during coredump.

6139864a4c esp_flash: fix coredump for legacy spi flash API
When legacy mode is used, the coredump still fails during linking
because "esp_flash_init_default_chip", "esp_flash_app_init" and
"esp_flash_default_chip " are not compiled and linked.

Instead of using ``if`` macros in callers, these functions are protected
by ``if`` macros in the header, and also not compiled in the sources.
"esp_flash_default_chip" variable is compiled with safe default value.
