For there're only laser ports on x550 before, we only considered laser
ports for the testpmd CLIs "port start/stop ...". Now we have new x550
devices which have copper ports. Use the API for copper to enable/disable
these ports.
And also let the testpmd CLI "set link-up/down ..." support copper
ports.
