lucid: add support to detect BC1.2 suppliers
Use built-in USB periperal to detect BC1.2 suppliers and update the
charge manager.
BUG=chrome-os-partner:48658
BRANCH=None
TEST=manual for lucid. Use a samus as the supplier, and insert the
charger into Lucid. Verify that it identifies it as SDP. Use a wall
charger and verify that Lucid identifies it as DCP.
