[PATCH 1/6] dt-bindings: pinctrl: renesas: rzg2l-pinctrl: Add interrupt-parent

[Fabrizio Castro <fabrizio.castro.jz@xxxxxxxxxxx>]

All the platforms from the renesas,rzg2l-pinctrl.yaml binding
actually require the interrupt-parent property. Add it.

Fixes: 35c37efd1273 ("dt-bindings: pinctrl: renesas,rzg2l-pinctrl: Document the properties to handle GPIO IRQ")
