This patch replaces all the filter coefficients to avoid the
unpleasant effect of samples saturation that the previous 0 dB max.
gain scaled coefficients could cause. The saturation of transients
may still happen but it should be more rare.
The filter coefficients scaling is changed from fixed pass band peak
align (to 0 dB) into DC gain controllable via new parameter gain in
src_param.m.

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.

This patch adds into filter tools retrieving of ABI version from a
single function (a quick solution) and updates all configuration
data tools to apply the user ABI header.
The confusing platform_max_channels struct field is renamed to
channels_in_config (the EQ channel map) that creates many updates. The
EQ response plot title is fixed.
Finally new functions to decode IIR and FIR settings blobs is added.
