mmc: sh_sdhi: Add SDHI support
R-Car Gen3 series have four SD card interfaces (SDHI0 to SDHI3),
two of which can also be used as MMC interfaces (SDHI2 and SDHI3).
This adds High-speed mode SD clock frequency between 25MHz and 50MHz,
8bit/4bit bus width, high capacity and low voltage device support.
