Modify board_set_active_charge_port to return status indicating whether the selected charge port was rejected. If rejected, zero out its available charge and attempt to select a different charge port. Also, reduce the length of related console prints. BUG=chrome-os-partner:34677 TEST=Manual on Samus. Plug C-to-Arec into port 1, verify that charge manager does not select port 1 as active and charging icon is not seen in OS. BRANCH=Samus.
