octopus npcx: ensure EC enters deep sleep when AP in S0
This change enables EC deep sleep in S0, which should give a power
savings of about 20 mW when the system is idle.
BRANCH=none
BUG=b:78225493
TEST=with yorp: ran "ectool version" 50k times with feature enabled
and saw no errors, plugged board into keyboard, trackpad, and
screen to ensure no apparent lag or keystroke loss occurred, ran
faft_ec suite and verified pass/fail rate was the same as without
feature
