Add support for parsing sink/source pin binding array per widget from topology. The pin binding arrays will be used to determine the source and sink queue IDs during widget binding for widget that requires special pin binding. An example of widget that requires special pin binding is the smart amplifier widget, its feedback sink pin has to be connected to a capture DAI copier for codec feedback, while the other sink pin has to be connected to a host DAI copier. Pin ID is required during widget binding for correct route setup. Conversely, the pin ID for 'generic' pins is not defined in the topology and will be allocated by the kernel dynamically. When only one pin is supported, the pin ID shall always be zero. When more than one pin is supported, the pin ID is determined with the ID allocation mechanism in the kernel.

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.
