dpaa: Add "libbsd,dedicated-portal" to QMan portals

By default, the network interfaces use a pool channel, see
dpaa_get_channel() in dpaa_eth_priv_probe().  To enable a dedicated QMan
software portal, use libbsd,dedicated-portal = "enabled";.  This option
is useful for special purpose 10Gbit/s Ethernet processing.

                                libbsd,dedicated-portal = "enabled";
                        };
                };
        };
};
