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

Currently glk kwd pipeline is set to run at 48kHz. This rate is wrong
and will create too big buffers and we will run out of memory. So set
the kwd pipeline rate to 16kHz.

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from pcm/dai rate and scheduling time the frame count is obsolete.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 fixes two things:
- Configures HDA pipelines to be timer driven.
- Moves definition of pipe-kfbm-capture to avoid overwrite
of deadline and frames for other pipelines.
