net: stmmac: Use driver data and callbacks tied with compatible strings

Browse Source 
The stmmac driver core allows passing feature flags and callbacks via
platform data. Add a similar stmmac_of_data to pass flags and callbacks
tied to compatible strings. This allows us to extend stmmac with glue
layers for different SoCs.
