arm64: dts: renesas: r9a07g043u: Update pinctrl node to handle GPIO interrupts

Add required properties in pinctrl node to handle GPIO interrupts.

Note as IRQC is not enabled in RZ/Five the phandle for interrupt-parent
is added in RZ/G2UL specific dtsi so that RZ/Five pinctrl driver
continues without waiting for IRQC to probe.
