a728c7cdd0 gpio/at91: auto request and configure the pio as input when the interrupt is used via DT
If we do this

	interrupt-parent = <&pioA>;
	interrupts = <7 0x0>;

The current core map the irq correctly but the gpio is not configured as input.
The pinctrl configure the pin as gpio with the correct mux parameter but is
not responsible to configure it as input.

So do it during the xlate

6732ae5cb4 ARM: at91: add pinctrl support
This is also include the gpio controller as the IP share both.
Each soc will have to describe the SoC limitation and pin configuration via
DT.

This will allow to do not need to touch the C code when adding new SoC if the
IP version is supported.
