commit be6f8db406a49511a8d213f9443ae79fe5b086c3 upstream.

The RZ/G1C (a.k.a. R8A77470) comes with three SDHI interfaces,
SDHI0 and SDHI2 are compatible with R-Car Gen2 SDHIs, and
SDHI1 is compatible with R-Car Gen3 SDHIs, as it comes with an
internal DMAC, therefore SDHI1 is fully compatible with driver
renesas_sdhi_internal_dmac driver. As a result, the compatible
strings for the R8A77470 SDHI interfaces are a little bit special.
Document SDHI support for the RZ/G1C SoC.
