Shawn Nematbakhsh c1fe8f2173 charge_manager: Store dualrole capability in charge manager 
Since charge manager is now informed of all capability changes as they
happen, it makes sense to store the port capability within charge manager,
rather than storing in pd.

BUG=chrome-os-partner:36390
TEST=Manual on Samus. Insert 1A Apple charger, verify correct detection.
Run 'chgoverride -2' to prevent charging, then repeatedly insert +
remove a dual-role charger on the other charge port. Verify that
charging is still prevented. Finally, insert a dedicated charger and
verify that the override is removed. Also, pass unit tests and verify
correct detection in various scenarios with various chargers.
BRANCH=Samus
