Add GPIO driver for the Aaeon SRG-IMX8P embedded controller. This
driver supports 7 GPO (General Purpose Output) pins and 12 GPIO pins
that can be configured as inputs or outputs.

The driver implements proper state management for GPO pins (which are
output-only) and full direction control for GPIO pins. During probe,
all pins are reset to a known state (GPOs low, GPIOs as inputs) to
prevent undefined behavior across system reboots, as the MCU does not
reset GPIO states on soft reboot.
