ASoC: SOF: intel: hda: add hw_params_upon_resume flag for hda stream
The prepare() ioctl for BE dai link gets called both
when the stream is started and when it is resumed from
suspend. SOF uses this ioctl to set the hw params
again only if the stream has been suspended.

When the stream is started, the hw_params ioctl gets called
before prepare() and hw_params is set for the BE dai link.
So the prepare call does not need to do anything further.

When the stream resumes after system suspend, SOF requires
that the hw_params be set again for the BE dai. In order
to determine which streams should set the hw params
during prepare(), an internal flag called "hw_params_upon_resume"
is introduced in struct sof_intel_hda_stream. The flag is set
for hda streams when the sof device suspends and is
cleared after hw_params is set.

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.
