amdgpu_bo_get_preferred_pin_domain was added to handle system memory

Well I would rather keep that and enable system memory page tables again.
We should probably add IOMMU checks to
amdgpu_bo_get_preferred_pin_domain() anyway. My last status is that this
has been causing problems with DC as well.
Alex, what do you think?
