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)
