Add 3 new topology IPC ops for widget_setup, widget_free and dai_config in order to make the pipeline management code IPC agnostic and implement the ops for IPC3. Use the newly introduced tplg dai_config op to configure the DAI during BE DAI hw_params and hw_free. Also, in preparation for IPC4, modify BE hw_params callback to skip setting up the DAI widget. All widgets will be set up during FW hw_params and the DAI_CONFIG IPC should be sent only if the widget use_count is > 0. With setting up/freeing removed from the BE hw_params, remove the configured flag as it is no longer needed.

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.
