The Allwinner sunxi mmc host uses dma in bus-master mode using a built-in
designware idmac controller, which is identical to the one found in the
mmc-dw hosts. However the rest of the host is not identical to mmc-dw, it
deals with sending stop commands in hardware which makes it significantly
different from the mmc-dw devices.

Add SD/MMC driver for MOXA ART SoCs.

The "MOXA ART MMC controller" is likely a faraday "ftsdc010",
a controller with support in U-Boot:

It turns now that the only really platform specific code that is needed for
SOCFPGA is using the SDMMC_CMD_USE_HOLD_REG in the prepare_command function.
Since the Rockchip already has this functionality, re-use the code that is
already in dw_mmc-pltfm.c.
