TCPC: Set charger vbus during init
For some chargers and TCPCs (specifically in this case, BC1.2 charger
and ANX7447 combination), the TCPC will not supply a power status
changed interrupt after waking from low power mode with the charger
plugged in. In this case, we can use the Vbus presence during init
in order to alert the charger task.
BUG=b:130249342
BRANCH=octopus
TEST=checked PD and BC1.2 chargers worked on both ports of phaser,
verified they also worked over resets and sysjumps, both locked and
unlocked
