drm/amd/pp: Add auto power profilng switch based on workloads (v2)
Add power profiling mode dynamic switch based on the workloads.
Currently, support Cumpute, VR, Video, 3D,power saving with Cumpute
have highest prority, power saving have lowest prority.
in manual dpm mode, driver will stop auto switch, just save the client's
requests. user can set power profiling mode through sysfs.
when exit manual dpm mode, driver will response the client's requests.
switch based on the client's prority.
v2: squash in fixes from Rex
