cam: Add actuator standalone diver for berlin

-To eliminate the resonance noise during system vibrator vibrating, set actuator to
specified DAC position(480 on GT9772), then the resonance noise can be obviously improved.
To achieve the conbination between vibrator and camera AF actuator,we implemnte:
- Actuator separately control during camera power off.
- Actuator policy to avoid vibrating disturb normal camera AF.
- reinitialize when the safe_pos parameter is manually configured.
