regulator: Set apply_uV only when min and max voltages are defined
apply_uV is errornously set when regulator is instantiated from device tree, even when it doesn't contain any voltage constraints. This commit fixes error: machine_constraints_voltage: CHARGER: failed to apply 0uV constraint for following regulator description in DTS: CHARGER { regulator-min-microamp = <100000>; regulator-max-microamp = <200000>; } Signed-off-by: Karol Lewandowski <k.lewandowsk@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
