[U-Boot] [PATCH 5/5] mmc: sh_sdhi: Add SDHI support

[Nobuhiro Iwamatsu <iwamatsu@nigauri.org>]

Hi,

> 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.
