Widget's parameters are set in topology and they usually consist of several different types of tuple arrays like strings, words and bytes. Here this kind of combination is called a "set". Lately we've seen more complex widget definitions with multiple identical sets of tuple arrays. One example is the dmic pdm configuration, which is currently handled as a special case in token parsing. This is not scalable for other components with multiple sets. So add a new function sof_parse_token_sets, which can be used to parse multiple sets. This function defines the number of sets and an offset to copy the tokens to correct positions in the destination ipc struct. Old sof_parse_token function will be a special case of calling sof_parse_token_sets to parse 1 set with offset 0. Finally modify the dmic dai link loading to use the new sof_parse_array_sets to load multiple pdm configs.

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.
