ASoC: codecs: wcd937x: add wcd937x codec driver

This patch adds basic SoundWire codec driver to support for
WCD9370/WCD9375 TX and RX devices.

The WCD9370/WCD9375 has Multi Button Headset Control hardware to
support Headset insertion, type detection, 8 headset buttons detection,
Over Current detection and Impedence measurements.
This patch adds support for this using wcd-mbhc apis.
