mkbp_event: Allow host to report sleep state for non-wake event skipping
Allow the host to self-report its sleep state through
EC_CMD_HOST_SLEEP_EVENT, which will typically be sent with SUSPEND
param when the host begins its sleep process. While the host has
self-reported that it is in SUSPEND, don't assert the interrupt
line, except for designated wake events.
BUG=chrome-os-partner:56156
BRANCH=None
TEST=On kevin, run 'ectool hostsleepstate suspend', verify that
interrupt assertion is skipped for battery host event. Run 'ectool
hostsleepstate resume' and verify interrupt is again asserted by the
battery host event.
