This patch adds to all DMIC related topologies the new token
SOF_TKN_INTEL_DMIC_UNMUTE_RAMP_TIME_MS. The value is set to 400
to correspond to 400 milliseconds long unmute ramp time. The
topology defined unmute will override the firmware internal
hard coded value if it is set in topology.

This patch replaces the -64 to 0 dB volume scale for capture with
more practical -50 to +30 dB gain. The step is 1 dB. It allows to
compensate for different microphone model sensitivities when constant
acoustical decibels to digital decibels level is needed in a
microphone capture application.

This patch fixes 2ch dmic capture topology. It appeared as topology
completion fail in SOF boot. The missing quote characters in m4
caused the STEREO_PDM0 macro triggered lines to no not be included
into conf file.

Use the same m4 files to generate both 2ch and 4ch topologies
by defining channels during compilation.
