mmc: sh_mmcif: revision-specific CLK_CTRL2 handling
Some newer MMCIF IP revisions contain a CE_CLK_CTRL2 register, that has to be set for proper operation. Support for this feature is added in a way to preserve the current behaviour by default, i.e. when it is not enabled in platform data. Patch is based on work by Nobuyuki HIRAI.
