commit 60ab43ba6b6e0f888aab3ce0f84a8aaf15d15079 upstream.

The RZ/G1C (a.k.a. R8A77470) comes with three SDHI interfaces,
SDHI0 and SDHI2 are compatible with the R-Car Gen2 SDHIs, SDHI1
is compatible with R-Car Gen3 SDHIs and it can be used as
eMMC as well. This patch adds driver compatibility, and makes
sure both drivers get compiled for the R8A77470.
