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.
