drm/amd/powerplay: add Vega10 powerplay support (v5)

Adds power management support for vega10.

v2: squash in fan control and led config fixes from Rex
v3: squash in dead code removal and socvid fixes from Rex
v4: squash in dpm force level fix from Rex
v5: squash in latest headless, gpu load fixes from Rex
