Hi All,

- RZ/G2UL and RZ/Five ("r9a07g043")
- RZ/G2L(C) ("r9a07g044")
- RZ/V2L ("r9a07g054")
- RZ/G3S ("r9a08g045")
- RZ/V2M ("r9a09g011")

The SD/MMC Interface in the above listed SoCs is not identical to that of
R-Car Gen3. These SoCs have HS400 disabled and use fixed address mode.
Therefore, we need to apply fixed_addr_mode and hs400_disabled quirks.
'renesas,rzg2l-sdhi' is introduced as a generic compatible string for the
above SoCs where fixed_addr_mode and hs400_disabled quirks will be applied.

v1->v2
- Updated commit messages for patch #1 and #2
- Dropped SoC DTSI changes as its a hard dependency
- Grouped single const value items into an enum list.
- For backward compatibility retained RZ/V2M compat string

v1: https://patchwork.kernel.org/project/linux-renesas-soc/cover/20240422213006.505576-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

Cheers,
Prabhakar
