Commit954a03be03("iommu/arm-smmu: Break insecure users by disabling bypass by default") intentionally breaks all devices using the SMMU in bypass mode. This is breaking various devices on Tegra186 which include the ethernet, BPMP and HDA device. Fix this by populating the iommus property for these devices with their stream ID.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
