Boards using the TWL6030 regulator may not all use the LDOs the same way. Some might also not use MMC1 at all, so VMMC would't have to be enabled. This delegates TWL6030 MMC power initializations to board-specific functions, that may still call twl6030_power_mmc_init for the default behavior. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
