Subject: [PATCH] Enable PMU during photo capture

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

Bug: 342502377
Test: GCA photo capture
