When a reset is done via SNVS state the PMIC OTP data is not reload. +# This causes power outputs that have been under SW control to stay down when +# reset has switched power state to SNVS. If reset is done via READY state the +# power outputs will be returned to HW control by OTP loading. Thus the reset +# target state is set to READY by default.
