Add support for SMMU drivers built as modules to the ACPI/IORT device probing path, by deferring the probe of the master if the SMMU driver is known to exist but has not been loaded yet. Given that the IORT code registers a platform device for each SMMU that it discovers, we can easily trigger the udev based autoloading of the SMMU drivers by making the platform device identifier part of the module alias.

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.
