Temporary OTG and external power support
This is only for initial bringup that requires OTG to boot kernel. Note
that we are expecting firmware for USB ID detection and hardware change
to charger chip, so this is likely going to be thrown away.
BUG=chrome-os-partner:21964
TEST=Plug in OTG dongle and check VBUS voltage is ~5V
TEST=Unplug and check it's ~0V.
BRANCH=None
