samus_pd: add dual-role port flag to power info host command

Browse Source 
Add flag for whether or not device plugged into a given port is a
dual-role PD device. For now, the dual-role flag is always 0, but
need to add the flag to the host command now for compatibility
in the future.

BUG=chrome-os-partner:32650
BRANCH=samus
TEST=load onto samus, run ectool --name=cros_pd usbpdpower and
verify that for anything plugged in it says "dedicated charger"
