Extcon: Arizona: Add driver for Wolfson Arizona class devices
Most Wolfson Arizona class audio hub CODECs include a flexible ultra low power accessory detection subsystem. This driver exposes initial support for this subsystem via the Extcon framework, implementing support for ultra low power detection of headphone and headset with the ability to detect the polarity of a headset. The functionality of the devices is much richer and more flexible than the current driver, future patches will extend the features of the driver to more fully exploit this.
