Bug description:
[Impact]
Screen flickering/tearing when AMD Stoney Ridge outputs to 4K display.
[Fix]
Disable IOMMU on Stoney Ridge.
[Test]
Connect to 4K screen through DP or HDMI. Heavy flickering/tearing can be
observed.
The flickering/tearing is gone once the patch is applied.
[Regression Potential]
Low. This fix limits to one specific SoC.
According to AMD, IOMMU isn't enabled for this SoC under Windows.
So it's expected behavior.
