Use CAMERA_STREAMING_VIDEO_CALL powerhint to optimize power for
the video_call use cases like Meet.

Upstream has fixed relationship between uclamp_min and margin which
means uclamp_min value between 80-100% of capacity of the CPU is a valid
value and will not cause upmigration.
To keep the current hints in powerhint.json the same, we must update
uclamp_min to be capacity_orig_of(medium_cpu) + 1.
This change is dependent on uclamp vs fits margin in GKI, vendor
modules. And an improvement in sched_pixel to ignore the 25% boost if
the only reason to request the frequency is uclamp_min.
To cater for the later - we multiply each uclamp_min value with 1.25
- except ones that look intentionally set around capacity boundaries.

Currently the CPU scheduler is not tuned to set the proper OPPs
for camera use cases so hard limiting the CPU frequencies to limit
the CPU power. This is just a temporary solution and should be
adjusted if it causes any perf regression.

For all the use-cases, restrict camera daemon to use
4 small and 4 mid cores by default.

Before PMU feature is ready, directly limit the CPU frequencies
via powerhint. Also update the value of CPU frequencies based on
the latest HW.
