Daisuke Nojiri 23149261dc system: Allow hibernate to clear AP_OFF flag ...

After firmware update, cr50 toggles the EC's reset line, expecting
the system will boot. This isn't the case for Chromebox because it
sets AP_OFF flag on a clean shutdown (to restore the previous power
state after power loss & restore).

This patch adds EC_REBOOT_HIBERNATE_CLEAR_AP_OFF to EC reboot
command. It makes EC first clear AP_OFF then hibernate.

BUG=b:69721737
BRANCH=none
TEST=Verify Fizz reboot after cr50 update.
