This patch adds the the Matlab script dmic_init() that simulates initialization of the Intel PDM digital microphones decimation block. The tool computes the needed FIR filters and exports them as C header files. The script dmic_batch computes all the currently used decimation settings. The generated header files from subdirectory include need to be manually copied to src/include/sof/audio/coefficients/pdm_decim/ and the header file pdm_decim_table.h edited manually if the header file names were changed due to different filter characteristic (band frequencies, stop-band attenuation).
