Compatible for XU4 audio is not being used. Instead the board uses the same compatible as XU3. The devices are now just compatible so they should use the same value. Mark "hardkernel,odroid-xu4-audio" as being deprecated so in this future could be removed to limit useless properties. Additionally add older compatibles appearing in the bindings.
