Commit 275dcd2 "ARM: dts: add max77686 pmic node for smdk5250" added
required LDO's for SMDK5250 boards.Currently LDO10 is turned off.As LDO10,
enable/disable the LDO22 which is required for VDDQ_MMC2_AP.So this patch 
makes LDO10 turn's on always.

always enabled? Shouldn't it be specified as one of the MMC regulators 
in corresponding MMC controller node?

Best regards,
Tomasz
