cheza: Check power enough and enable PP5000 when power-on AP
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.
