[PATCH] DT: mmc: sh_mmcif: fix "compatible" property text

The "compatible" property text contradicts even the example given in the MMCIF
binding document itself; moreover, the Renesas MMCIF driver only  matches  on
the generic "compatible" string, and doesn't look for at SoC specific strings
currently at all. Thus describe "renesas,sh-mmcif" string as mandatory and the
others as optional.
