This reverts commit 9a45ac2320d0a6ae01880a30d4b86025fce4061b.
This was added a helper for amdgpu to workaround a runtime pm regression
caused by a runtime pm fix in efifb. We now have a better workaround
in amdgpu in
commit f95af4a9236695 ("drm/amdgpu: don't runtime suspend if there are displays attached (v3)")
so this workaround is no longer necessary. Since amdgpu was the only
user of this interface, we can remove it.

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.
