ASoC: SOF: Intel: hda-ctrl: only clear WAKESTS for HDaudio codecs
When a PME wake happens due to a SoundWire wake, we currently clear
all WAKESTS bits during the resume operation initiated by the PCI
subsystem. As a result, we are unable to identify which SoundWire
links need to be resumed and don't properly handle jack detection.

This patch only clears the WAKESTS bits for the HDaudio codecs
detected earlier.

Note that we still clear all WAKESTS bits unconditionally in
hda_dsp_ctrl_stop_chip(). The existing behavior is potentially racy if
e.g. a jack event happens during a suspend routine, but there's a risk
of breaking shutdown or reboot sequences so the code is left as is for
now.

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 reStructuredText 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.
