net: dsa: mv88e6xxx: add support for bridge flags

Add support for the bridge flags to Marvell 88e6xxx bridges, allowing
the multicast and unicast flood properties to be controlled.  These
can be controlled on a per-port basis via commands such as:

	bridge link set dev lan1 flood on|off
	bridge link set dev lan1 mcast_flood on|off
