The previous patch added PCI ports array, to store the associated netdevice
for each local port. Add APIs which set/unset netdevice for specific local
port, these APIs will be used from mlxsw_sp_port_create() and
mlxsw_sp_port_remove(). For now, store only netdevice pointer, next patches
will extend this structure.
