UCM2: sof-soundwire: Enable DRC and equalizers for

This patch enables SOF post-processing for soundwire speaker
output. The DRC processing is enabled as BootSequence, and
setup of DRC, IIR, and FIR equalizer blobs as FixedBootSeqeuence
by DMI ID if custom blobs have been defined for the device in
ucm2/blobs/sof/product_configs or ucm2/blobs/sof/user_configs.

The DRC can be turned off permanently by user space if not
desired since BootSequence is only used for first time UCM2
start.

The DRC, IIR, FIR blobs are set as FixedBootSequence only
if custom blobs are defined. Otherwise the blobs defined in
topology remain in use.
