Remove the previous hack of force increasing the adapter current. The PP5000 rail is now turned on/off during power-on/off AP. Add a check to ensure it has enough power to enable the 5V rail and boot AP. If the battery is in low level or unplugged and the charger adapter doesn't supply enough power, don't boot AP and transition back to S5. The check may wait a while for PD negoiation. BRANCH=none BUG=b:79353631 TEST=On battery plugged and unplugged cases, checked the device can source VBUS to USB port-0 and port-1. TEST=Unplug battery and use a low-power adapter, can't boot up AP. See the "Not enough power to boot" message and transition to S5.
