net: hns: add attribute port-idx-in-ae in enet node.
This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6
PHYs of service DSAF are taken as ethernet ports to the CPU. The
port-idx-in-ae can be 0 to 5. Here is the diagram:
+-----+---------------+
| CPU |
+-+-+-+---+-+-+-+-+-+-+
| | | | | | | |
debug debug service
port port port
(0) (0) (0-5)
In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical
ports connect to a LAN Switch while the CPU side assume itself have one
single NIC connect to this switch. In this case, the port-idx-in-ae will
be 0 only.
+-----+-----+------+------+

when port-idx-in-ae is not exists, old attribute port-id will be used
(only for compatible purpose, not recommended to use port-id in new code).
