This setting is only used if the SPI flash pins have been overridden by setting the eFuses
SPI_PAD_CONFIG_xxx, and the SPI flash mode is QIO or QOUT.
When this is the case, the eFuse config only defines 3 of the 4 Quad I/O data pins. The WP pin (aka
ESP32 pin "SD_DATA_3" or SPI flash pin "IO2") is not specified in eFuse. The same pin is also used
for external SPIRAM if it is enabled.
If this config item is set to N (default), the correct WP pin will be automatically used for any
Espressif chip or module with integrated flash. If a custom setting is needed, set this config item to
Y and specify the GPIO number connected to the WP.

help
This value is ignored unless flash mode is set to QIO or QOUT *and* the SPI flash pins have been
overriden by setting the eFuses SPI_PAD_CONFIG_xxx.
The option "Use custom SPI Flash WP Pin" must be set or this value is ignored
When this is the case, the eFuse config only defines 3 of the 4 Quad I/O data pins. The WP pin (aka ESP32
pin "SD_DATA_3" or SPI flash pin "IO2") is not specified in eFuse. That pin number is compiled into the
bootloader instead.
The default value (GPIO 7) is correct for WP pin on ESP32-D2WD integrated flash.
If burning a customized set of SPI flash pins in eFuse and using QIO or QOUT mode for flash, set this
value to the GPIO number of the SPI flash WP pin.
