Currently, SOF probes machine drivers by creating a platform device and passing the machine description as private data. This is driven by the ACPI restrictions. Ideally, ACPI tables should contain the description for the machine driver. This is not possible because ACPI tables are frozen and used on multiple OS-es (e.g Windows). In the case of Device Tree we don't have this restriction, so we choose to probe the machine drivers by creating a DT node as is the standard ALSA way. This patch makes the probing of machine drivers from SOF core optional allowing for Device Tree platforms to decouple the SOF core from machine driver probing. Along with this, it also consolidates the machine driver selection for Intel platforms by defining optional ops for selecting the machine driver based on the ACPI match for HDA and non-HDA platforms and setting the mach params.

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.
