Zhaoqi Xu 081e55461e arch/xtensa/esp32s3: Make SPI CS, MOSI and MISO pins signed. 
The CS, MOSI and MISO pins can be set to -1 in Kconfig when the board
does not use them, and esp32s3_spi_init() skips a pin when it is
negative. The pins are stored as uint8_t in esp32s3_spi_config_s, so
-1 becomes 255, every "pin >= 0" check is always true, and 255 is
passed to esp_gpiowrite() and esp_configgpio(), which trips their
DEBUGASSERT.

Store these three pins as int8_t so -1 is kept and the existing checks
work.

Fixes apache/nuttx#20186
