mmc: renesas-sdhi: Flag non-standard SDnH handling for V3M
V3M handles SDnH differently than other Gen3 SoCs, so let's add a
separate entry for that. This will allow better SDnH handling in the
future.
Based on Linux commit 627151b4966f ("mmc: renesas_sdhi: Flag
non-standard SDnH handling for V3M") by Wolfram Sang
