Simple driver for Hifiberry and ICS43432 MEMS microphone compatible hardware

AoSC Driver Simple I2S Hifiberry and ICS43432 MEMS

Use Hifiberry-dac / Adafruit Speaker Bonnet and ICS43432 / SPH0645 I2S MEMS Mic simultaneously

Tested with:

• Adafruit I2S MEMS Microphone Breakout
• Adafruit I2S 3W Stereo Speaker Bonnet for Raspberry Pi

Based on googlevoicehat-{codec,soundcard}.c by Peter Malkin.
