That won't work. Devicetree provides a slightly flexible promise of
backwards compatibilty. So a new kernel should still work old devicetrees.
(not exactly sure if this means dt-binaries and sources or only binaries)

So while I think RK_FUNC_0-n should not be used anymore, we should
probably just mark them as "deprecated" in a first step.
