> Extend the S32G2 SIUL2 pinctrl binding to describe the GPIO data and
> external interrupt resources present in the same SIUL2 hardware block.
>
> Besides the MSCR and IMCR registers used for pin multiplexing and pad
> configuration, SIUL2 also contains PGPDO and PGPDI registers
> for GPIO data and EIRQ registers for external interrupt control.
>
> Add GPIO controller properties because the SIUL2 block also provides
> GPIO functionality, and gpio-ranges are needed to describe the
> mapping between GPIO lines and pin controller pins.
>
> Document the interrupt controller properties. The SIUL2 block
> contains EIRQ hardware as part of the same register space. IRQ support
> itself will be added in a follow-up patch series.
>
> Update the example accordingly to show the complete SIUL2 register
> layout, including the GPIO data and EIRQ register windows.
