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 Change-Id: If1a59a3232e2f9a49f272c6dee5319254d87b9a9 Signed-off-by: Alec Berg <alecaberg@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/213371 Reviewed-by: Randall Spangler <rspangler@chromium.org>
