Update DeviceAutoUpdateTimeRestrictions policy description

DeviceAutoUpdateTimeRestrictions policy has been updated in the update
engine code. It now supports cancelling an ongoing update when a
restricted time interval specified in the policy starts. The scope of
the policy is no longer limited to just kiosk mode. The policy is not
applicable in case of update from version lower than minimum Chrome OS
version, quick fix build update, enterprise rollback and interactive
update.
