The SDHI/eMMC IPs found with the RZ/V2M (a.k.a. r9a09g011), are
very similar to the ones found in R-Car Gen3, but they are not
exactly the same, and as a result need an SoC specific compatible
string for fine tuning driver support.

The RZ/V2M comes with 2 SDHI interfaces and 1 eMMC interface.
Add the relevant nodes to the SoC specific device tree.

I'll just ignore the overlap...
I couldn't review the clock parents, as that information seems to
be restricted, but the rest LGTM.

i.e. will queue in renesas-devel for v6.3.
Note that this causes "make dtbs_check" failures, due to a bug in
