[PATCH 5/8] drm/amdgpu: move priority decay logic into amd_sched_priority_ctr

[Christian König]

Sorry for the delay, back from a rather long sick leave today and trying 
to catch up with my work.

Please keep it simple and stupid. No extra fiddling here, that stuff is 
complicated enough.

So I would strongly suggest to have a simple set interface which the DRM 
master can use to set the priority.

If we have multiple DRM masters which feel responsible for this they 
should to sync up in userspace what to do.

Christian.
