ASoC: max98095: add jack detection
This change adds the logic to support using the jack detect mechanism built in to the codec to detect both when a jack was inserted and what type of jack is present. This change also supports the use of an external mechanism for headphone detection. If this mechanism exists, when the max98095_jack_detect function is called, the hp_jack is simply passed NULL. This change supports both simple headphones, powered headphones, microphones and headsets with both headphones and a mic.
