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.
