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.
