SM5803: Only enable auto charge when battery is connected
When the battery is physically present, but still in a disconnected
state the board may brown out once the battery connects and the charger
chip believes the end of charge condition is met. Only start auto
charging bits when the battery has connected.
BRANCH=None
BUG=None
TEST=on waddledee starting with cutoff battery, board doesn't brownout
when battery connects
