[PATCH 1/2] ASoC: dt-bindings: tegra: Document iommus and interconnects for ADMAIF

[Thierry Reding <thierry.reding@xxxxxxxxx>]

From: Thierry Reding <treding@xxxxxxxxxx>

The ADMAIF is responsible for accessing system memory on behalf of other
components of the APE, so make sure it can be hooked up to an IOMMU and
memory controller.
