[PATCH] dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2N SoC

[PATCH] dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2N SoC

[Prabhakar]

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

Document support for the DU IP found on the Renesas RZ/V2N (R9A09G056) SoC.
The DU IP is functionally identical to that on the RZ/V2H(P) SoC, so no
driver changes are needed. The existing `renesas,r9a09g057-du` compatible
will be used as a fallback for the RZ/V2N SoC.
