Make DeviceIdle motion sensing flaggable-off
We will still go through the same routine as before, and in particular
a misconfigured phone without any motion sensors will still fail to
progress into full doze state.
With config_autoPowerModeUseMotionSensor overriden to false, this is not
true any more and we make STATE_SENSING a no-op that moves straight into
STATE_LOCATING as if we immediately got a "no motion" callback.
