DSA is not Marvell only, so please remove these from struct dsa_port and
place them somewhere like struct mv88e6xxx_port. Also, the change has
nothing to do in a patch with the "net: switchdev: " prefix.

As mentioned by Ido, please update br_switchdev_fdb_populate() as part
of this change, in the bridge->switchdev direction. We should add a
comment near struct switchdev_notifier_fdb_info stating just that,
so that people don't forget.
