power: ADPF: make uclamp.min stable

Considering the previous uclamp.min value is the base of PID output.
Instead of:
  `next_min = std::min(sUclampMinHighLimit, output);`
We should use:
  `next_min = std::min(sUclampMinHighLimit, current_min + output);`

When session status entered stale state, set the uclamp to 0, but keep
the current_min. That would be helpful for boosting the heavy workload
of the first few frames.

Bug: 204444691
Test: build && manual test
