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 after TURN_UPDATE_ON command. BUG=b:69721737 BRANCH=none CQ-DEPEND=CL:802632 TEST=Verify Fizz reboot after cr50 update.
