Controller needs to ensure display power is enabled only for
HDA controller reset. Drop the display power-up/down calls from
D0i3 entry/exit paths.
This was previously not possible as codec drivers could not resume the
links, and instead controller kept the reference to display power. The
state of display power had be maintained in the D0i3 entry/exit code.
With commit 87fc20e4a0 ("ASoC: SOF: Intel: hda: use hdac_ext
fine-grained link management"), this is no longer needed and the code
can be cleaned up.

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.
