ARM: 5721/1: MMCI enable the use of a regulator

Browse Source 
This enables the use of a regulator to power the MMCI/PL180
PrimeCell. The OCR mask is calculated and voltage is set using
the new MMC core functions for discovering voltage ranges
in regulators. The platform translate_vdd function which basically
controls the 4 lines out of the PL180 is disabled if you use a
regulator instead.
