Enable PMU during photo capture

Browse source 
This CL enables PMU feature during photo capture. With the new settings, we can achieve up to 120ms saving in capture latency, while paying a penalty of 60mW. However, even with the added power, we are still below the F10 numbers (go/f10-camera-power-gtw).

Refer to ag/27238472 and ag/27255676
