Reinhard Panhuber 9b2ddd9cc6 Generalize audio driver for 3 audio functions plus a lot more.
- Audio format and parameters are parsed from descriptors thus user no
longer needs to give them explicitely

- Tested for 4 channel software type I PCM encoding with 16 bit with 1
channel per FIFO and 2 channels per FIFO (this is I2S specific)

Jerzy Kasenberg a5581b10df audio: Add headset example
This example code creates USB Audio 2.0 headset device.
Device has two audio interfaces first stereo speaker
with 48kHz stereo stream.
Second interface for microphone with 48kHz mono stream.

This example can be used to start working on audio device.
It can be also used to verify ISO endpoints for boards.

Speaker adaptive clock (bound to SOF).
Microphone for now has asynchronous clock.

Volume and mute control while present are not used for data stream
modification.
