net: mscc: ocelot: publish structure definitions to include/soc/mscc/ocelot.h

We will be registering another switch driver based on ocelot, which
lives under drivers/net/dsa.

Make sure the Felix DSA front-end has the necessary abstractions to
implement a new Ocelot driver instantiation. This includes the function
prototypes for implementing DSA callbacks.
