Add multicast filtering support for VLAN interfaces in HSR offload mode for ICSSG driver. The driver calls vlan_for_each() API on the hsr device's ndev to get the list of available vlans for the hsr device. The driver then sync mc addr of vlan interface with a locally mainatined list emac->vlan_mcast_list[vid] using __hw_addr_sync_multiple() API. The driver then calls the sync / unsync callbacks. In the sync / unsync call back, driver checks if the vdev's real dev is hsr device or not. If the real dev is hsr device, driver gets the per port device using hsr_get_port_ndev() and then driver passes appropriate vid to FDB helper functions.
