net: stmmac: Allocate and pass soc/board specific data to callbacks
The current .init and .exit callbacks requires access to driver
private data structures. This is not a good seperation and abstraction.
Instead, we add a new .setup callback for allocating private data, and
pass the returned pointer to the other callbacks.
