The call to the mmc_power_up during the mmc_start_host breaks the card
detection in design-ware host controller. This patch removes the call to
mmc_power_up function during host start.
This fix works fine with sdhci (sdhci compatilble host controller)
and dw_mmc (design-ware host controller). and has no side effect due to
this removal.
Tested on : origen-board and smdk-5250 board.
