Add new PowerAdvisor interface for SF to pass hints to the power HAL.
GPU composition is slow with FP16 wide color gamut. In this patch, we try to
mitigate this issue by boosting the GPU to higher frequency when SurfaceFlinger
is going to switch to Display P3 color mode by sending the new
PowerHint::EXPENSIVE_RENDERING to PowerManager.
BUG: 110112323
Test: adb shell cat /sys/class/kgsl/kgsl-3d0/devfreq/cur_freq to verify GPU
frequency with/without WCG content. GPU frequency should be high with
WCG content, and should be reset without WCG content.
