576e0ec26b drm/amdgpu: fix xgmi perfmon a-b-a problem 
Mapping hw counters per event config will cause ABA problems so map per
event instead.

v2: Discontinue starting perf counters if add fails.  Make it clear what's
happening with pmc_start.

bdf84a80e0 drm/amdgpu: Create generic DF struct in adev 
The only data fabric information the adev struct currently
contains is a function pointer table. In the near future,
we will be adding some cached DF information into adev. As
such, this patch creates a new amdgpu_df struct for adev.
Right now, it only containst the old function pointer table,
but new stuff will be added soon.
