ARM: DRA7x/AM57x: Add MMC/SD fixups for rev1.0 and rev 1.1

Browse source 
Since DRA7xx/AM57xx SR1.1 and SR1.0 has errata to limit the frequency of
MMC1 to 96MHz and frequency of MMC2 to 48MHz for AM572x SR1.1, limit the
frequency and disable higher speed modes for those revision.
Also use the recommended IO delays (those tagged with "rev11")
