arm64: dts: renesas: r9a09g087: Add ICU support 



The Renesas RZ/N2H (R9A09G087) SoC has an Interrupt Controller (ICU) block
that routes external interrupts to the GIC's SPIs, with the ability of
level-translation, and can also produce software and aggregate error
interrupts.

Add support for it.
