UCM2: sof-soundwire: Enable DRC and equalizers for speaker

This patch adds to soundwire speaker output enable of DRC processing
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.
