soc/mediatek/mt8186: Enable VRF12 software control for MT6366

VRF12 does not provide power to PS8640 on krabby.
In original patch, VRF12 is not used, and is set to hardware control
for low power. We change the setting to remove hardware control.
Therefore, if we want to control VRF12 by software, we can control
it directly.

BUG=b:210806060
TEST=build pass
