[ Upstream commit 3f1271b54edcc692da5a3663f2aa2a64781f9bc3 ]

There are enough VBIOS escapes without the proper workaround that some
users still hit this.  Microsoft never productized ATS on Windows so OEM
platforms that were Windows-only didn't always validate ATS.

The advantages of ATS are not worth it compared to the potential
instabilities on harvested boards.  Disable ATS on all Navi10 and Navi14
boards.

Symptoms include:

  amdgpu 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0007 address=0xffffc02000 flags=0x0000]
  AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0007 address=0xffffc02000 flags=0x0000]
  [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, signaled seq=6047, emitted seq=6049
  amdgpu 0000:07:00.0: amdgpu: GPU reset begin!
  amdgpu 0000:07:00.0: amdgpu: GPU reset succeeded, trying to resume
  amdgpu 0000:07:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring sdma0 test failed (-110)
  [drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block <sdma_v4_0> failed -110
  amdgpu 0000:07:00.0: amdgpu: GPU reset(1) failed
