This patch adds DMIC0_ENHANCED_CAPTURE=true to function topologies for PCH DMIC. The function topology is used in a SDW platform if there is a PCH DMIC in use instead of SDW codec connected microphone. The microphone pre-processing adds the multi-microphone beamformer (TDFB) and dynamic range compressor (DRC) components. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
