As opposed to earlier incarnations, the memory controller on Tegra186 no
longer implements an SMMU. Instead the SMMU is a regular ARM SMMU and in
a separate IP block.
However, the memory controller programs the SMMU stream IDs for each of
the memory clients. Add a header file with definitions for each of these
stream IDs and mark the #iommu-cells property as required on Tegra30 to
Tegra210 in the device tree bindings.
