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

Extend the RIIC driver to support the RZ/V2H ("R9A09G057") SoC. It
accomplishes this by appending the compatible string list and passing
the RZ/V2H-specific OF data.

Additionally, this patch introduces an riic_family enum for SoC variants,
replacing macro previously used.
