While the AMD IOMMU is only available on x86 today, there is nothing
x86-specific in its architecture, so I don't think its header files
belong to arch/x86.

By that reasoning we could also move all of the intel gpu stuff to
arch/x86. But we don't do it, because it doesn't make sense and because
it doesn't belong there.
