ASoC: SDCA: Add SDCA FDL data parsing

Add parsing of ACPI DisCo information specific to FDL (File DownLoad).
DisCo contains a list of File Sets which can be requested by the device
and within each of those a list of individual files to be downloaded to
the device. Optionally the contents of the files may also be present in
a special ACPI table, called SWFT (SoundWire File Table).
