When test is run with enabled coverage, additional RAM is required
to store coverage data.
Digital Microphone test is reserving most of the available RAM
to store audio samples. Thus, test fails to build with coverage
enabled due to RAM overflow.
Decrease size of the audio buffer when coverage is enabled.

Add DMIC API test, intended to verify DMIC drivers are functioning
correctly within the DMIC API.

- Stereo channel audio
- Using maximum number of channels supported by DMIC IP
