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.
