The version of VIC found in Tegra186 and later incorporates improvements with regards to context isolation. As part of those improvements, stream ID registers were added that allow to specify separate stream IDs for the Falcon microcontroller and the VIC memory interface. While it is possible to also set the stream ID dynamically at runtime to allow userspace contexts to be completely separated, this commit doesn't implement that yet. Instead, the static VIC stream ID is programmed when the Falcon is booted. This ensures that memory accesses by the Falcon or the VIC are properly translated via the SMMU.
