iommu/tegra: gart: Integrate with Memory Controller driver
The device-tree binding has been changed. There is no separate GART device anymore, it is squashed into the Memory Controller. Integrate GART module with the MC in a way it is done for the SMMU on Tegra30+. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
