GPIO drive strength flags

The drive strength flags are a Zephyr specific extension of the standard GPIO flags specified by the Linux GPIO binding.

Only applicable for Espressif ESP32 SoCs.

The interface supports two different drive strengths: DFLT - The lowest drive strength supported by the HW ALT - The highest drive strength supported by the HW

#define ESP32_GPIO_DS_DFLT   (0x0U << ESP32_GPIO_DS_POS)
 Default drive strength.
 
#define ESP32_GPIO_DS_ALT   (0x3U << ESP32_GPIO_DS_POS)
 Alternative drive strength.
