This patch adds to IIR EQ capability to convert from s32 source to
s16/s24/s32 sink formats in normal PCM samples equalization. The
feature is useful in microphone equalization where input dynamic
range is high but where pipeline needs to be lower word length. A
typical IIR high-pass response when combined with gain will reduce
the dynamic range by suppressing lowest frequencies from signal to
better fit the smaller sample word length.
The PCM capability in topology macro pipe-eq-capture.m4 is changed to
allow the s16/s24/s32 formats.
The patch also includes 4096 bytes increase to SOF_TEXT_SIZE for CNL
platform.

This patch updates the provided example responses as data for
sof-eqctl and in the include files for topologies. The updates into
Matlab scripts are included also. The FIR and IIR example script is
updated to contain all examples.
The patch includes also a bug fix into IPC handler where the check
against SOF_IPC_MSG_MAX_SIZE is off by one and caused it to reject
all set data commands (to the EQs).

This patch adds 50 kHz into SRC generator script for std and tiny
profiles. The src generator script is cleaned up and the default
conversion matrix is moved into caller script for easier maintenance.
The plots appearance is improved and the generated coefficients code
look is improved to pass the git pre- and post-commit script
requirements.
The SRC test bench scripts are updated for changed locations. A SRC
playback topology is used for test bench and real device usage.

By default topology is using too many capture and playback PCMs, DAIs and
pipelines for available host GW DMAC channels. Comment out some so that
DMAC channels stay within bounds. This also gives users options to
re-enable for theer given test HW.

The requirement for DMIC capture is to support upto 4ch
and 16-bit format. So modify the topology accordingly.

Somehow those two files should only differ on SSP connections and MCLK
ID1, so it's pretty obvious no one has tested this since August...

Fix the issue that ipc timeout when simutalously playback
and capture. Now in FW, playback and capture are supported
by different dai. So dai index should be different for playback
and capture in the same be dai, or playback would use the same
dai as capture

This patch adds the ABI header into topology EQ data files and updates
the pipe-eq-volume-playback.m4 to include the coefficients from m4
directory like other topology files to prevent duplication of
response data.
The CONTROLBYTES_MAX is decreased to 304 due to larger IPC header size.
The update is not critical since the kernel contains other checks to
cover this. However it's done to avoid confusion.

Modify hard-coded virtual widgets to prevent kernel
warnings generated by the machine driver. No need to
add virtual_dapm_routes. Just adding the required virtual
widgets suffices to suppress the warnings.
