dt-bindings: pinctrl: sunxi: Make interrupts optional

The R_PIO pinctrl device on the Allwinner H616 SoC does not have an
interrupt (it features only two pins).
However the binding requires at least naming one upstream interrupt,
plus the #interrupt-cells and interrupt-controller properties.

Drop the unconditional requirement for the interrupt properties, and
make them dependent on being not this particular pinctrl device.
