Use the dGPU path instead.  There were a lot of platform
issues with IOMMU in general on these chips due to windows
not enabling IOMMU at the time.  The dGPU path has been
used for a long time with newer APUs and works fine.  This
also paves the way to simplify the driver significantly.

v2: use the dGPU queue manager functions

We are dropping the IOMMUv2 path, so no need to enable this.
It's often buggy on consumer platforms anyway.

Use local64_try_cmpxchg instead of local64_cmpxchg (*ptr, old, new) == old
in amdgpu_perf_read.  x86 CMPXCHG instruction returns success in ZF flag,
so this change saves a compare after cmpxchg (and related move instruction
in front of cmpxchg).

Also, try_cmpxchg implicitly assigns old *ptr value to "old" when cmpxchg
fails. There is no need to re-read the value in the loop.

No functional change intended.
