pd: treat externally powered dualrole devices as dedicated chargers
Treat externally powered dualrole devices as dedicated chargers.
This allows us to default to consuming power from externally powered
dualrole devices and cancels a charger override when one is attached.
BUG=chrome-os-partner:38785
BRANCH=samus
TEST=tested with third-party dualrole device that can be externally
powered.
also tested with another samus that was hard-coded with externally
powered bit set, and deleted it's policy for power swapping. when
this externally-powered samus is plugged into a samus running this CL,
we always charge from the externally-powered samus.
