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.
