Document the Qualcomm WCD9390/WCD9395 Audio Codec and the Soundwire devices than can be found on Qualcomm SM8650 based platforms.

The Qualcomm WCD9390/WCD9395 Audio Codec communicates with the host SoC over 2 Soundwire links to provide: - 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

The WCD9390/WCD9395 IC has separate I2C subsystem for USB-C DP Altmode/Audio Accessory mode Mux which is not documented here but requires port/endpoint graph and properties to handle Altmode/Audio Accessory switch and orientation.

When the WCD codec is connected behind an USB-C audio mux, plug/unplug events, clock control, pull-up and threshold are different. Add a typec_analog_mux config enabling those changes and add two callbacks to trigger plug/unplug events from USB-C events.

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.
