The audio tests signals contain a start and end marker to extract the
test output to analyze from in-between the markers.
This patch fixes a fail in SRC tests that was caused by incorrect
synchronization to output data. The chirp upper frequency is limited
to 0.99 x Nyquist frequency since the Nyquist frequency in the end
aliased and caused a visible artefact to spectral plot and it triggered
a resampler filter impulse response that had some correlation with
start/end marker chirps. The cosine chirp initialization to start from
90 degrees (zero PCM code instead of max.) also cleaned the start impulse
and improved the look of spectrogram plot.
The syncronization was limited to seek from one measured channel only. The
sync finder also didn't handle properly multi-channel input.
The output file start marker scan length was reduced to be
idle+marker length. And the scan time for end was reduced to be
2xidle+marker length

This patch extends the allowed sample rate range to 8 - 192 kHz, and
channels count to 1 - 16. Previously only 48 kHz and 2 - 4 channels was
allowed.

This patch increases the SRC source buffer to contain 5 periods of data
(measured for 1 ms @ 48 kHz ). It fixes the issue in 176.4 kHz to 48 kHz
playback conversion that the pipeline freezes with insufficient available
data in source buffer for SRC to convert and too little free in buffer
for host to fill another 48 frames.
176.4 kHz playback is currently the largest buffer size consumer due
to non-steady in/out rate. The higher rate conversion 192 kHz to 48 kHz
can operate with smaller size buffer due to steady in/out rate.
Note: This has been only simulated in the host test bench since SRC
playback does not run currently in real devices due to another issue.
However since buffers simulation is accurate this should be a real issue.

The topology files naming has been updated to include mclk-N so it
needs to be added here as well for the script src_run.sh to work.

This patch provides tests for sample rate converter (SRC) SOF component.
The tests are executed via the SOF host (x86) version test executable and
the SRC component library.

This patch modifies the test topology generator to add dmic topologies
with pre-defined PDM controller configurations, sample rates and
formats.
It also modifies the DMIC_CONFIG macro to get the number of
active pdm from the pdm config.

This patch adds the scripts src_std_int32.m and src_tiny_int16.m those
were used to create the conversions matrices for the default and tiny
profiles. The scripts call the included src_generate function that
does the task with help from the filter design and coefficients
export utilities.
The quality and resources consumption of SRC can be customized with
this tool.
