dt-bindings: memory: Add Tegra186 support
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.
