plankton: Set polarity when connected
When a cable is connected, set USBC_POLARITY to the right polarity. This
is done in a different way than how we do this on other boards because
we only want to control polarity automatically on cable connection.
BUG=chrome-os-partner:32163
TEST=Flip the cable, check USBC_POLARITY changes.
BRANCH=None
