scarlet: Use TCPC to detect if AC is present
After VBUS is up, there is a delay of ~500ms for rt946x to determine
'VBUS is ready'.
But we need charger_task to detect AC presence and then set a proper
sleep time immediately.
When using fusb302 to detect VBUS, I almost don't see any delay.
BUG=b:71520398
BRANCH=none
TEST=Confirm BATTERY LED turns on immediately when AC is
plugged in a Scarlet in G3.
