MANATEE: HACK: platform/chrome: ignore EC_HOST_RESUME_SLEEP_TIMEOUT
In ManaTEE, system may not be able to wakeup from idle sleep.
If the host can't enter s0ix during s2idle, CrOS EC sets
EC_HOST_RESUME_SLEEP_TIMEOUT flag in response to host event
HOST_SLEEP_EVENT_S0IX_RESUME.
Upon wakeup, powerd picks this up from cros_ec/last_resume_result in
sysfs, and tries to suspend the system again, for up to
/usr/share/power_manager/retry_suspend_attempts.
This patch ignores EC_HOST_RESUME_SLEEP_TIMEOUT flag to prevent powerd
from suspend retries.
Additional fix to call cros_ec_fixup_s0ixwake_mask() from CrOS guest
only.
BUG=b:228433429
TEST=idle suspend from powerd and able to wake up even if EC reports
suspend timeout.
