net: ethernet: ti: cpsw: unsync mcast entries while switch promisc mode
After flushing all mcast entries from the table, the ones contained in mc list of ndev are not restored when promisc mode is toggled off, because they are considered as synched with ALE, thus, in order to restore them after promisc mode - reset syncing info. This fix touches only switch mode devices, including single port boards like Beagle Bone.
