commit 24be0b3c40594a14b65141ced486ae327398faf8 upstream.
This reverts commit 4baf1218150985ee3ab0a27220456a1f027ea0ac.
Enabling runtime pm as default for all AMD xHC 1.1 controllers caused
regression. An initial attempt to fix those was done in commit a5d6264b638e
("xhci: Enable RPM on controllers that support low-power states") but new
issues are still seen.
Revert this to get those AMD xHC 1.1 systems working
This patch went to stable an needs to be reverted from there as well.
Fixes: 4baf12181509 ("xhci: Loosen RPM as default policy to cover for AMD xHC 1.1")

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.
