CONFIG_GPIO_MMIO32

This is a driver for accessing a simple, fixed purpose, 32-bit memory-mapped i/o register using the same APIs as GPIO drivers. This is useful when an SoC or board has registers that aren’t part of a GPIO IP block and these registers are used to control things that Zephyr normally expects to be specified using a GPIO pin, e.g. for driving an LED, or chip-select line for an SPI device.
