[PATCH] ASoC: samsung: Mark unused Odroid compatibles as deprecated

[Krzysztof Kozlowski]

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 future could be removed to limit useless compatibles.

Additionally add older compatibles appearing in the bindings.
