This patch adds support to define from CMakeLists.txt or a
higher level platform topology file the definition of DMICPROC and
DMIC16KPROC to select desired capture processing algorithms pipeline
from pipe-x-capture.m4 and pipe-x-capture-16khz.m4 macros instead
of hard coded processing eq-iir-volume. It is preparation to add
support for beamformer processing for microphones.
The impacted platforms are sof-hda-generic, sof-cml-rt5682, and
sof-apl-pcm512x. This patch does not change built topologies.

icl, cml whl are sharing some toplogy files. Create platform specific files
including DSP configuration, SSP setting and DMIC to simplify platform
settings.

Pipeline PCM0P and PCM0C in sof-cml-rt5682-kwd.m4 is wrongly
configured. This patch fix this error by removing redundent
'SSP' argument.

DMIC01 is just useless for a user. After multiple rounds of
discussion, we agreed to remove numbers (which could be understood as
a mic position) or a frequency (which is misleading since it can be
updated to e.g. 96kHz by topology), so by default the DMIC interface
is called just that...
Conversely, we add a clear 16kHz qualifier for the low-frequency
path. While in theory the frequency can be changed with modifications
of the FIR filter, applications do need 16kHz support.
Also make sure we only use 'DMIC' for 'PCH-attached DMICs'. For
RT715-based solutions, the microphones can be analog, so use more
generic 'Microphones' description.

Reverts all previosly changed cAVS pipelines from 3 to 2 periods.
Now we have separate buffers for DMA, so there is no need to make
DAI buffers consist of 3 periods. DMA will take care of any internal
hardware requirements.

Switches all pipelines for cAVS platforms to timer scheduling.
This way we limit the number of interrupt levels processed
in the system. Timer, IPC and IDC are already on level 2 and
DMAs are on level 5.

Changes number of SSP, DMIC and ALH 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from pcm/dai rate and scheduling time the frame count is obsolete.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.

As dmic only support 16 bit or 32 bit, we configure dmic dai to be
s32_le, and pipelines to be s24_le.
