[PATCH 6.12.y-cip 2/4] dt-bindings: i2c: renesas,riic: Document RZ/V2N (R9A09G056) support

[Ovidiu Panait]

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

commit 8b284979f7fb2f1acfd88a6b96c8863c410eb27f upstream.

Document support for the I2C Bus Interface (RIIC) found on the Renesas
RZ/V2N (R9A09G056) SoC. The RIIC IP is identical to that on RZ/V2H(P),
so `renesas,riic-r9a09g057` will be used as a fallback compatible,
enabling reuse of the existing driver without changes.
