For K3-J721e devices, gpio virtualization is achieved by
replicating copies of GPIO controller.
Each cell gets a dedicated GPIO controller. However, there is
additional field in the pinctrl to select the GPIO group.
Add the mem_regions for main_gpio2 and main_gpio3
Program gpio_group in the pinctrl node for SW10 gpio_keys
