in this patchset, enet specifies a reference to dsaf. and delete the
ae-name in enet, and adds parsing the ae-handle from DT to set the
associating with dsaf.
the patchset updates the dtsi and bindings documents as well.

1.9.1
enet is associating with dasf. before this patch, the association is
the same strings between ae-name and dsa-name. in a general way, enet
specifies a reference to dsaf should be a good idea. so this patch
deletes the ae-name in enet, and adds parsing the ae-handle
from DT to set the associating with dsaf.

This change breaks compatibility with old dtbs. IIRC, this is all new,
so maybe it doesn't matter, but you should be explicit that you are
doing that.
