imx: only define deprecated symbols conditionally

Define deprecated symbols in an #ifdef IMX_NEEDS_DEPRECATED_SYMBOLS ...

All files that still depend on the old definitions get
-DIMX_NEEDS_DEPRECATED_SYMBOLS passed to the compiler.

When all remaining users are fixed this allows including the soc
specific headers unconditionally.
