Rather than _FOR_MODULES, how about using a namespace.
https://docs.kernel.org/core-api/symbol-namespaces.html#how-to-use-symbols-exported-in-namespaces
Add a name space "NET_PHY_CORE_ONLY", and put these symbols into that
name space. We should notice any driver importing that namespace and
reject it.
