This patch add regulator suspend state to constraint in dt file. The regulation_
constraints structure already has regulator suspend state field as following.
The regulator suspend state control the state of regulator according to
PM (Power Management) state.
- struct regulator_state state_disk
- struct regulator_state state_mem
- struct regulator_state state_standby
