If a regulator consumer requests a voltage range that can be satisfied, the return value should indicate success even if that regulator has a fixed voltage. Since there is already logic to check if the requested voltage range overlaps the allowed range, set REGULATOR_CHANGE_VOLTAGE for regulators with constraints that include a positive voltage.
