* [PATCH] arm64: tegra: Enable audio IOMMU support on Tegra194

From: Thierry Reding <treding@nvidia.com>

Add iommus and interconnects properties to the sound device tree node on
Tegra194. This ensures that the correct SID is used for translation of
physical to I/O virtual addresses and that the path to system memory is
properly described, which in turn can impact the range of memory that
the device can address.
