mci: dw_mmc: socfpga: Supply bus-width in platform_data

Since there is no OF support in the xloader on socfpga it uses the
platform_data system.  There needs to be a way to supply the
equivalent of the DT property bus-width this way to support devices
that need to use a smaller bus.

So that we don't need to put every flag that might get added to the
MMC_CAP list into platform_data, just put the bus width ones into
platform_data.

The socfpga dts sources specify a bus-width of 4 so use that in the
platform_data for socfpga.
