tools: tune: Add tools to generate ctrl bytes for Crossover
This commit adds the tools to generate the control bytes for the
crossover component. To generate the control bytes, run the
example_crossover.m script.
The parameters of the crossover components are:
- number of outputs
- sink assignments (routing crossover output to different pipelines)
- frequency cutoffs
To tweak the parameters modify the values in example_crossover.m and run
it.
Refer to sof/src/include/user/crossover.h for more information on how
the crossover config is structured and how sink assignments are done.

sof: crossover: Add Crossover component
This commit adds Crossover to the list of SOF components. A crossover
filter can be used to split an input to different frequency bands.
The number of outputs should be set statically in the topology. The user
then uses the control bytes to route the frequency bands to different
outputs. (similar to the demux component).
This commit adds support for the following formats:
- S16_LE
- S24_LE
- S32_LE

sof: eq_iir: modularize iir_df2t() function
This commit extracts the biquad processing from iir_df2t(). It allows to
reuse the biquad processing code independently of the equalizer
implementation.
Components such as crossover use biquads for processing input.
But it could not do so because iir_df2t() was specific to single output
audio processing.
The motivation behind this change was to reuse the
coefficients of the LR4 biquads for the crossover more freely. An LR4
filter is made of two biquads in series with same coefficients.
Therefore to save memory, we can store one copy of each set of
coefficient, and pass those to the biquad processing function.

Testbench: Check tplg_read_array() error codes in topology parsing
This patch adds the missing error codes check to avoid the parsing
to continue after a possible file I/O fail.
