[Fix] Disable PCI ATS for the device. [Test] After applying the patch, there's no more IOMMU error, and the driver can correctly probe the device. The grahpics also works great. [Regression Potential] Low. amdgpu is known to work well with ATS disabled. In addition to that, AMD confirmed it's the correct fix for this card, so the chance to break anything is rather low.
