ARM: OMAP: hsmmc: Support for AM3517 MMC1 voltages
This patch fixes the following error message which appears while intializing MMC1 on the AM3517 EVM base-board: mmc0: host doesn't support card's voltages mmc0: error -22 whilst initialising SD card The ocr_mask, which enumerates the volatges supported by the MMC card was not being indicated before, assuming that a separate Vcc regulator maybe another controllable regulator driver would be doing this. This patch statically specifies a subset of the voltages supported by the MMC driver, which are provided by the current fixed voltage regulator on AM3517 EVM.
