[PATCH v4 5/5] 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.
