This does not solve the selected pins issue. For example, you don't know
if it's sdmmc1_dat1.sdmmc1_dat1 or gpmc_ad9.sdmmc_dat1. That selection
is board specific.
So you either have to pass the selected pins from the board-*.c file,
or do the muxing in board-*.c file. It depends on the the case.
How about take a look at specifying the pin names in board-*.c in
struct omap_mmc_platform_data?
