range 0 33

---help---
This value is ignored unless flash mode is set to DIO or DOUT and
the SPI flash pins have been overridden by setting the eFuses
SPI_PAD_CONFIG_xxx.
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. And the psram only
has QPI mode, the WP pin is necessary, so we need to configure
this value here.
When flash mode is set to QIO or QOUT, the PSRAM WP pin will be
set as the value configured in bootloader.
For ESP32-PICO chip, the default value of this config should be 7.

* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a
* mode enumeration value, a set of DIP switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
