gpio: TODO: add a task for removing MMIO-specific fields from gpio_chip
Currently for CONFIG_GPIO_GENERIC=y each struct gpio_chip object contains the fields relevant only for gpio-mmio users. It's not an insignificant number either as it's several pointers and integers. It makes sense to remove these fields from struct gpio_chip into a dedicated structure but this is not trivial due to how the bgpio_init() function is implemented. Add a task for tracking this rework.
