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.

This patch adds topology sof-apl-src-dmic.m4 to test capture SRC.
The topology instantiates SRCs for 48 -> 8-48 kHz and 16 -> 8-48 kHz
capture. The volume component in pipeline handles PCM format
conversion from the fixed S32_LE DMIC DAI format. Also the bugs in
the earlier non-used pipeline macro are fixed.
The macro pipe-src-capture.m4 is renamed to pipe-src-volume-capture.m4
since it contains a volume component. A new macro pipe-src-capture.m4
is created to provide pipeline building block without volume.
