  1. Tools: Topology1: Add MFCC component 

    This patch adds basic macros needed for MFCC in testbench and in
developmemnt topologies for hda-generic-2ch and up2. The
configuration blob in this matches the reference Matlab code
as configured to match Pytorch default MFCC.

  3. Tools: Tune: Matlab tool for creating configuration blob for MFCC 

    This patch adds initial version of MFCC setup tool setup_mfcc.m. It
outputs a configuration topology macro file that matches the current
Matlab concept code. The configuration can be tested in testbench
with the supplied scripts run_mfcc.sh and decode_ceps.m.

  4. Tools: Tune: Prevent topology1 blob export to increase blob size 

    The increase of non-32bit aligned blob sizes needs to be removed
because it can cause mismatch of blob binary header vs. actual
size. Instead error if blob size is not multiple of four bytes.

  5. Audio: Add audio feature extractor component MFCC 

    This patch adds the SOF component for Mel Frequency Cepstral
Coefficients (MFCC) streaming to sink from source PCM stream.
The MFCC audio features are commonly used for neural network
based speech recognition services.
