dt-bindings: mmc: renesas,sdhi: Document RZ/G2L family compatibility 



- 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.

Document 'renesas,rzg2l-sdhi' as a generic compatible string for the
above SoCs.

Also now use the 'renesas,rzg2l-sdhi' string in the if check for making
sure the required clocks are present.
