pd: Ensure PD is interrupted on EC reset
If PD is negotiated and the EC is reset, a source partner port will
continue providing its negotiated voltage (eg. 20V in the case of
zinger). Ensure the partner port is in a known state by providing Rp
for a brief period after resetting to RO.
BUG=chrome-os-partner:62281
BRANCH=Reef
TEST=On kevin, attach zinger, wait for 20V negotiation, and press F3 +
power to cause EC reset. Verify VBUS drops to approximately 0V before
going back to 5V / 20V. Verify the same with kevin OEM charger as well.
Also verify kevin boots with no battery.
