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().

Applied to u-boot-net/network-master Thanks, Ramon.
