Daniel DeGrasse c4e48b66bd tests: drivers: audio: add dmic API test
Add DMIC API test, intended to verify DMIC drivers are functioning
correctly within the DMIC API.

The test verifies the following:
- Mono channel audio
- Stereo channel audio
- Using maximum number of channels supported by DMIC IP
- Pausing/restarting channels
- Checks to make sure invalid channel maps are rejected by the DMIC.

DMIC API Test
##################
This test is designed to verify that DMIC peripherals implement the API
correctly. It performs the following checks:
* Verify the DMIC will not start sampling before it is configured
* Verify the DMIC can sample from one left channel
* Verify the DMIC can sample from a stereo L/R pair
* Verify that the DMIC works with the maximum number of channels possible
(defined based on the DTS compatible present in the build)
* Verify that the DMIC can restart sampling after being paused and resumed
* Verify that invalid channel maps (R/R pair, non-adjacent channels) are
rejected by the DMIC driver.
