Ensure doze sensors can be registered when screen on.

Prior to this, the sensors were always off if the screen was on. This
meant that if a notifciation came in, the phone wouldn't react to
being picked up (the screen would show the notification but otherwise
remain dim). With this change, the phone can now wake up.
