Changes number of SSP and DMIC DAI periods from 2 to 3.
This way we can support both timer and new single DMA
channel scheduling.

Enable setting pcm min and max rate from top level m4 pipeline macro.
This way it is possible to configure the whole pipeline to correct
samplerate range in 1 file. Previously you needed to modify the pipeline
macros where the rate was hardcoded. As the frame count is calculated
from pcm/dai rate and scheduling time the frame count is obsolete.
Introduce pipeline rate parameter to help configuring components with
fixed output rate. We can't deduce this from pcm range since for example
src might accept bigger max rate than the following dai. Even though the
parameter is named "pipeline rate" it essentially means the "final"
output rate to which this pipeline is connected to (dai or other
pipeline). In capture pipelines it means the originating fixed dai rate.

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.
