samus: add ability for PD MCU to send host event to AP
Add host event for PD up to AP. The PD toggles a gpio line to
EC causing an interrupt on EC. The EC then sends host command
down to PD MCU to get its status. There is a new status bit for
PD host event, so when EC see's the PD host event status bit,
it sends a PD host event to the AP.
There is currently only one host event for PD to AP.
BUG=chrome-os-partner:31361
BRANCH=none
TEST=added PD console command pdevent, which initiates the host
event. when sent, verified on EC that it sets the correct host
event bit using hostevent console command
