[PATCH v2] dt-bindings: i3c: renesas,i3c: Add RZ/V2H(P) and RZ/V2N support

[Prabhakar]

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

Add device tree binding support for the I3C Bus Interface on Renesas
RZ/V2H(P) and RZ/V2N SoCs. The I3C IP on these SoCs is identical to
that found on the RZ/G3E SoC.

Add new compatible strings "renesas,r9a09g056-i3c" for RZ/V2N and
"renesas,r9a09g057-i3c" for RZ/V2H(P). Both variants use
"renesas,r9a09g047-i3c" as a fallback compatible to indicate hardware
compatibility with the RZ/G3E implementation.

Update the title to be more generic as it now covers multiple SoC
families beyond just RZ/G3S and RZ/G3E.
