This patch modifies script example_dblock.m to create in
addition to existing default coefficients blob with parameter
R=0.98 a set of blobs those provide (-3 dB) cut-off frequencies
20, 30, 40, 50, 100, 200 Hz for 16 kHz and 48 kHz for various
usages. Human understandable parameters for blobs helps to select
the configuration for the needed dcblock usage.
The parameter value R for given frequencies is calculated
with iterative function dcblock_rval_calculate(). A closed
form equation might be possible to derive from the transfer
function. If such is found this function can be replaced with
quicker equation -- or with more advanced faster converging
iteration.
The topology blob export functions are also modified to add
comment line for exact build command.

This patch changes a bit structure of example_drc to export
conveniently several different blobs. The changed script
exports configurations blobs for disabled and enabled mode.
Two functions for IPC4 and topology2 compatibility are
generalized from EQ to common directory. The EQ and other
tools will be updated to later to use the common get_abi()
and tplg2_write() functions.
