ASoC: soc-acpi: introduce new 'machine check' callback

Browse Source 
The existing machine_quirk() returns a pointer to a soc_acpi_mach
structure.
For SoundWire/SDCA support, we need a slightly different
functionality where a quirk function either validates or NACKs an
initial selection, based on additional firmware/DMI information.
