Subject: [PATCH] Update power hint for camera workload

1) Enable prefer_high_cap of camera vendor group
2) Set high_capacity_start_cpu to 4
3) Set prefer_idle of camera vendor group to 0
4) Set MemFreq floor
5) Change camera-daemon/cpu.uclamp.latency_sensitive owner to root

Bug: 186564130
Test: Boot & check setting values
