EQ: Update ABI version number in configuration to match current version 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).

# Flat IIR EQ 18-Dec-2018
Topology: Add DMIC capture pipeline with gain and high-pass filter This patch adds topology sof-apl-eq-dmic to help testing acoustical audio capture via DMIC or work as example for other machine drivers. The capture format is set as four channels, S32_LE, 48 kHz. The IIR EQ is a 2nd order Butterworth high-pass with cut-off frequency at 50 Hz to suppress non-audible lowest frequencies. The EQ provides additional +20 dB gain to avoid the recording to sound too silent. The IIR EQ or additional FIR EQ instance can when needed provide other form factor specific equalization.

Tools: Topology: Update EQ related topology files for new user ABI 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.
