Your driver doesn't actually do anything beyond what is in the common
sdhci-pltfm.c infrastructure. IMHO you really shoulnd't need a SoC
specific abstraction for it at all and instead add a generic
platform driver registration into sdhci-pltfm.c. I'd suggest
you use "generic-sdhci" (similar to what we do for usb-ohci and usb-ehci
now) as the compatible string and change your device tree to claim
compatibility with that and your soc-specific string.
