[git pull] vmwgfx-fixes-5.0-2

[Thomas Hellstrom]

Dave, Daniel

A patch set from Christoph for vmwgfx dma mode detection breakage with the
new dma code restructuring in 5.0

A couple of fixes also CC'd stable

Finally an improved IOMMU detection that automatically enables dma mapping
also with other vIOMMUS than the intel one if present and enabled.
Currently trying to start a VM in that case would fail catastrophically.
