wm8996_detect - Enable default WM8996 jack detection

The WM8996 has advanced accessory detection support for headsets. This function provides a default implementation which integrates the majority of this functionality with minimal user configuration.

This will detect headset, headphone and short circuit button and will also detect inverted microphone ground connections and update the polarity of the connections.
