Currently, RK809's BUCK3 regulator is modelled in the driver as a configurable regulator with 0.5-2.4V voltage range. But the voltage setting is not actually applied, because when bit 6 of PMIC_POWER_CONFIG register is set to 0 (default), BUCK3 output voltage is determined by the external feedback resistor. Fix this, by setting bit 6 when voltage selection is set. Existing users which do not specify voltage constraints in their device trees will not be affected by this change, since no voltage setting is applied in those cases, and bit 6 is not enabled.
