> Add GPIO driver for the Aaeon SRG-IMX8P embedded controller. This

> 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.
