Add a new powerhint mode to boost GPU in shots on P22.

In P22 (Pro), there is no scaling_min_compute_freq (b/228921300) and under STREAMING_STANDARD setting GPU min frequency is 302000 which is smaller than scaling_min_compute_freq 471000 on P21 (Whi).

In addition, on Pro GPU we expect 25~30% slow down in the same frequency compared to Whi.

To boost the performance of GPU for shots on Pro, we add a new powerhint mode GCA_CAMERA_SHOT_GPU_EXTREME which raises the GPU frequency to the maximum.
