The device-tree binding has been changed. There is no separate GART device

I think this could technically have been two patches, but since they'd
have a compile-time dependency either way they need to be applied in the
correct order, so some coordination between IOMMU and Tegra trees is
going to have to happen anyway and might as well just stick this into a
single patch.
