[PATCH v3 7/9] arm64: tegra: Use correct compatible string for Tegra186 SMMU

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

The SMMU found on Tegra186 requires interoperation with the memory
controller in order to program stream ID overrides. The generic ARM SMMU
500 compatible is therefore inaccurate. Replace it with a more correct,
SoC-specific compatible string.
