regulator: tps65910: Configure correct value for VDDCTRL vout reg
As per datasheet, the voltage output is defined as from SEL[6:0] = 3 to 64 (dec) Vout= (SEL[6:0] × 12.5 mV + 562.5 mV) The list_voltage returns the vout as 600mV + selector * 12.5mV and so equivalent VSEL is selector + 3. Adding 3 on selector when configuring VSEL register for VDDCTRL output. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
