cr50: Make EC clear AP_OFF before hibnernate
This patch makes AP send EC_REBOOT_HIBERNATE_CLEAR_AP_OFF, which
makes EC clear AP_OFF flag then hibernate.
This is needed to make Chromebox boot when cr50 toggles the
EC's reset line.
BUG=b:69721737
BRANCH=none
TEST=Verify Fizz reboot after cr50 update.
