ALSA: hda: cs35l41: Support systems with missing _DSD properties
Some systems using CS35L41 with HDA were released without some
required _DSD properties in ACPI. To support these special cases,
add an api to configure the correct properties for systems with
this issue.
This initial commit moves the no _DSD support for Lenovo
Legion Laptops (CLSA0100, CLSA0101) into a new framework which
can be extended to support additional laptops in the future.
