mkpb: Add MKBP support over ACPI
Add a host event to support MKPB:
When sent, the ACPI code will send a notification to the kernel
cros-ec-lpcs driver that will issue EC_CMD_GET_NEXT_EVENT.
We can allow code (sensor stack for instance) that uses MKBP to work
on ACPI based architecture.
Obviously, host event over MKPB is not supported.
BRANCH=none
BUG=b:27849483
TEST=Check we get sensor events on Cyan through the sensor ring.
(cyan branch)
