MKBP event signalling implementation
This implements a new API for EC modules to define MKBP event sources
and send MKBP event to the AP. Also, a new host command
EC_CMD_GET_NEXT_EVENT is added for the AP to query the pending MKBP
events. Each event type may have custom event data sent along with the
event.
BRANCH=None
BUG=chrome-os-partner:33194
TEST=Enable MKBP event on Ryu. Set a host event from EC console, run
'ectool nextevent', and see MKBP event 0x01 (HOST_EVENT) and the set
host event.
