samus_pd: add more host events and host cmd to get event status
Add support for more host events and add a host command for the host
to use to get which host events have fired. The EC only uses one
real host command to notify the AP whenever the PD MCU needs attention
so the EC_CMD_PD_HOST_EVENT_STATUS host command can be used to
differentiate the possible triggers for the host event.
Current events include: PD remote device needs update, type-C power info
changed, and PD identity response received.
Added host event for power info change, which fires whenever a charger
or device is plugged into a type-C port.
BUG=chrome-os-partner:32650
BRANCH=samus
TEST=tested on samus by connected various peripherals to type-C ports
and verifying on EC console that a host event is sent.
