Add a function handler for the struct regulator_ops .set_mode so an
operating mode (opmode) can be set for regulators.
Regulators opmode are defined using the generic REGULATOR_MODE_*
modes so the driver maps these generic modes to the device-specific
operating modes as stated in the hardware data-sheet.
