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.
