[U-Boot] [PATCH] keystone2: net: add mcast function to keyston2 Ethernet driver

[Vitaly Andrianov]

The MCAST_TFTP support requires that network drivers has mcast functon
implemented. This commit adds dummy keystone2_eth_bcast_addr() to meet
the requirement. As far as the driver doesn't use ALE and doesn't filter
any incoming packets, the function is empty.
