dt-bindings: xilinx: Deprecate header with firmware constants

Firmware contants do not fit the purpose of bindings because they are not
independent IDs for abstractions. They are more or less just contants which
better to wire via header with DT which is using it.
That's why add deprecated message to dt binding header and also update
existing dt bindings not to use macros from the header and replace them by
it's value. Actually value is not relevant because it is only example.

The similar changes have been done by commit 9d9292576810 ("dt-bindings:
pinctrl: samsung: deprecate header with register constants").
