net: dsa: mv88e6xxx: make switchdev DB ops generic
The MDB support for the mv88e6xxx driver will be very similar to the FDB support, since it consists of loading/purging/dumping address to/from the Address Translation Unit (ATU). Prepare the support for MDB by making the FDB code accessing the ATU generic. The FDB operations now provide access to the unicast addresses while the MDB operations will provide access to the multicast addresses.
