net: dsa: introduce a .port_probe() method in struct dsa_ops
Some drivers might want to execute code for each port at probe time, as
opposed to executing code just-in-time for the port selected for
networking.
To cater to that use case, introduce a .port_probe() callback method
into the DSA switch operations which is called for each available port,
at the end of dsa_port_probe().
