We're going to add more different device controls (such as hearing aids presets, volume offset controls or microphone volume controls) into "device_controls_general" PreferenceCategory. It's better to keep the category controller separated from the child controller to better maintain the visibility of the whole category and have a clearer stucture of these controllers.
