[PATCH net-next 1/4] net: dsa: mv88e6xxx: add port private structure

[Vivien Didelot]

Add a per-port mv88e6xxx_priv_port structure to store per-port related
data, instead of adding several arrays of DSA_MAX_PORTS elements in the
mv88e6xxx_priv_state structure.

It currently only contains the port STP state.
