net: dsa: b53: Add support for MDB
In preparation for supporting IGMP snooping with or without the use of
a bridge, add support within b53_common.c to program the ARL entries for
multicast operations. The key difference is that a multicast ARL entry
is comprised of a bitmask of enabled ports, instead of a port number.
