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 Change-Id: Ie9c581a7b5a21c093a10d3e8d57cf27ac48fa138 Signed-off-by: Diana Z <dzigterman@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/1565170 Reviewed-by: Jett Rink <jettrink@chromium.org>
