From: Thierry Reding <tred...@nvidia.com>
Collapses the old memory-controller and IOMMU device tree nodes into a
single node to more accurately describe the hardware.
Note that this is an incompatible change, but while a GART driver has
existed for a few years it has never been used to do any translations.
