[Jean-Jacques Hiblot]

SDIO is not supported in u-boot, there is no point in enabling mmc3.

Tom, 

this will fix the problem youreported with commit b5511d6cb8dc601efc14b8cf60755
on am335x-evm. For the record, the problem is that the clock of mmc 3 is not
enbled by the arch code. With DM_MMC enabled, mmc3 gets probed and u-boot crashes
when mmc3's registers are accessed for the first time.

Jean-Jacques
