glados_pd: add initial support for glados PD
Initial support for glados PD. Charging and PD
communication only work on port 0.
BUG=none
BRANCH=none
TEST=make BOARD=glados, make BOARD=glados_pd
Connect hoho to glados and verify power contract successful.
Connect zinger to glados and verify power contract and
charging.
