[PATCH v3 2/4] dt-bindings: arm: fsl: fix DEBIX binding

[Marco Felsch]

The current imx8mp-debix-model-a.dts uses all three compatibles. Fix the
corresponding bindings by adding an own entry for it. Mark
polyhex,imx8mp-debix as deprecated but keep it within the dts file since
we already have a user for it [1].
