ASoC: codecs: Add WCD939x Codec driver 



Add the main WCD9390/WCD9395 Audio Codec driver to support:
- 4 ADC inputs for up to 5 Analog Microphones
- 4 DMIC inputs for up to 8 Digital Microphones
- 4 Microphone BIAS
- Stereo Headphone output
- Mono EAR output
- MBHC engine for Headset Detection

It makes usage of the generic MBHC and CLSH generic code and
the USB Type-C mux and switch helpers to gather USB-C Events
in order to properly setup Headset Detection mechanism
when connected behind the separate USB-C Mux subsystem.

WCD9390/WCD9395 supports a PCM path for Playback instead
of the actually implemented PDM playback, it will be
implemented later.
