Subject: [PATCH] dt-bindings: interrupt-controller: renesas,rzv2h-icu: Document RZ/V2N SoC support

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Document the Interrupt Control Unit (ICU) on the Renesas RZ/V2N SoC,
which is architecturally identical to the ICU used on the RZ/V2H(P)
SoC.
