net: dsa: sja1105: register switch before assigning port private data
Like the dsa_switch_tree structures, the dsa_port structures will be
allocated on switch registration.
The SJA1105 driver is the only one accessing the dsa_port structure
after the switch allocation and before the switch registration.
For that reason, move switch registration prior to assigning the priv
member of the dsa_port structures.
