The SDHI block on the RZ/Five SoC is identical to one found on the RZ/G2UL
SoC. "renesas,sdhi-r9a07g043" compatible string will be used on the
RZ/Five SoC so to make this clear and to keep this file consistent, update
the comment to include RZ/Five SoC.

No driver changes are required as generic compatible string
"renesas,rcar-gen3-sdhi" will be used as a fallback on RZ/Five SoC.
