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.

- clock-names: Must include the following entries:
- mc: the module's clock input
- interrupts: The interrupt outputs from the controller.
Required properties for Tegra30, Tegra114, Tegra124, Tegra132 and Tegra210:
- #iommu-cells: Should be 1. The single cell of the IOMMU specifier defines
the SWGROUP of the master.
