From: Anton Vorontsov <avorontsov@xxxxxxxxxx>
Sometimes want to place SoC-specific parts alongside with the generic
driver, and to do so, we have to switch the driver over to the module
device table matching.
Note that drivers/mmc/host/sdhci-pltfm.h is so far empty, but it'll hold
SoC-specific driver data handlers soon.
