Evan Quan a9c103fa91 PCI: Mark AMD Navi14 GPU ATS as broken
commit e8946a53e2a698c148b3b3ed732f43c7747fbeb6 upstream

Observed unexpected GPU hang during runpm stress test on 0x7341 rev 0x00.
Further debugging shows broken ATS is related.

Disable ATS on this part.  Similar issues on other devices:

README

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.
