Integrate charge_manager and include several API changes designed for reporting voltage. 1. Make pd_choose_voltage set the chosen voltage for use by caller. 2. Add voltage parameter to pd_set_input_current. 3. Add pd_get_role to grab the sync / source state of a port. 4. Add charge manager PD + type C port initialization to the pd state machine. BUG=chrome-os-partner:32003 TEST=Manual on samus. Insert Apple charger, verify charge limit is selected appropriately. Insert PD charger, verify that charge port switches to PD port. Remove + reinsert chargers, verify that port / limit is selected appropriately. Remove battery, insert power source, verify that our power source port never becomes disabled.
