net: dsa: mv88e6xxx: move call to mv88e6xxx_mdios_register()

Browse source 
Call the rather expensive mv88e6xxx_mdios_register() at the beginning of
mv88e6xxx_setup(). This avoids the double call via mv88e6xxx_probe()
during boot.

For symmetry, call mv88e6xxx_mdios_unregister() at the end of
mv88e6xxx_teardown().
