Remove PM functions at start/stop streaming, add PM helper functions
to get PM before encoding frame start and put PM after encoding frame
done. Meanwhile, remove unnecessary clock operations.

Those are exactly the same functions as the DECODER counterpart... instead
of duplicating them, can you please simply commonize the functions in
