mmc: renesas_sdhi: Add RZ/V2H(P) compatible string

The SD/MMC block on the RZ/V2H(P) ("R9A09G057") SoC is similar to that
of the R-Car Gen3, but it has some differences:
- HS400 is not supported.
- It has additional SD_STATUS register to control voltage,
  power enable and reset.
- It supports fixed address mode.

To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057'
compatible string is added.

Note for RZ/V2H(P), we are using the `of_rzg2l_compatible` OF data as it
already handles no HS400 and fixed address mode support. Since the SDxIOVS
and SDxPWEN pins can always be used as GPIO pins on the RZ/V2H(P) SoC, no
driver changes are done to control the SD_STATUS register.
