Add support for mmc on MT7988 SoC.

Signed-off-by: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>

There's no need to add yet one more duplicate mtk_mmc_compatible platform
data, nor one more compatible string to this driver, as this is exactly
the same as mt7986.

Please reuse the MT7986 compatible; in DT you'll have:

compatible = "mediatek,mt7988-mmc", "mediatek,mt7986-mmc";

Cheers,
Angelo
