Subject: [PATCH net 1/2] net: ethernet: ti: am65-cpsw-nuss: Update port_mask while adding multicast entry

Multicast entry rules are mainly evaluated for receiving traffic and do not
require MAC ports to be explicitly associated with them. However, setting
associated MAC port's bit to the port_mask of the ALE entry ensures
technical correctness and helps maintaining ALE entries linked to MAC
ports.
