regulator: palmas: configure enable time for LDOs
As per datasheet (Referred TPS65913), the on-time for LDO is 500micro second. If LDO6 is in vibrator mode then the on-time is 2000us. Set the enable_time on regulator descriptor accordingly. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
