DMIC: Add PDM microphones (DMIC) support to DAI

Browse Source

This patch adds the DMIC audio capture driver for SOF DAI component use.
The DMIC feature allows to directly attach one to (typically) four PDM
digital microphones into Intel SoC without a separate codec IC. This is
supported by APL and most successor platforms.

Corresponding patches are needed for kernel driver and topology to enable
this feature.
