From: Viswanath Puttagunta <vishp@xxxxxx>
MMC_CAP_UHS_DDR50 is SD card feature and not
eMMC feature. We don't have to check for this flag
to enable DDR on MMC. Checking for MMC_CAP_1_8V_DDR host capability
is sufficient.
This patch is needed for OMAP4 platforms as hsmmc can support DDR
with eMMC but does not support UHS speed mode for SD card.
