x1e80100 has an SMMUv3 connected to PCIe which is normally controlled by Gunyah and is thus transparent to the OS. However if we boot Linux in EL2, without Gunyah, we need to manage this IOMMU ourselves. To make that easier, and since the hardware actually exists, just not "usually" managed by Linux, describe it in the dts as "reserved".

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 reStructuredText 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.
