There are some Dell SKUs that need to set the parameters of the crossover filter (biquad).
Each amplifier connects to one tweeter speaker and one woofer speaker.
We should control HPF/LPF to output the proper frequency for the different speakers.
If the codec driver got the BQ parameters from the device property, it will apply these 
parameters to the hardware.

Shuming Fan (4):
  ASoC: rt1308-sdw: get BQ params property and apply them
  ASoC: rt1316-sdw: get BQ params property and apply them
  ASoC: Intel: sof_sdw_rt1308: add BQ params for the Dell models
  ASoC: Intel: sof_sdw_rt1316: add BQ params for the Dell models
