charger/rt946x: Reset VBUS by default
In the system, RT946x is always powered by the battery.
So even in battery cutoff mode, the reg values on RT946X are not reset.
We don't want RT946x to supply VBUS when DUT boots, which could mess up
PD state. So we need to disable VBUS output when RT946x initializes.
BUG=b:72228350
BRANCH=none
TEST=Confirm OPA_MODE (bit0 in reg 0x01) is clear after RT946x
finishes initialization
