camera power hint: raise CPU clock more conservatively at STREAM_HIGH mode

During streaming high fps mode, the BW is high and lead to CPU memory
high latency. This hint tries to avoid raising the CPU clock
at the condition when CPU is waiting for data access.

(cherry-pick from device/google/gs101)
Bug: 205010238
Bug: 184583714
Test:
