mv88e6060: disable hardware level MAC learning

Browse Source 
[ Upstream commit a74515604a7b171f2702bdcbd1e231225fb456d0 ]

Disable hardware level MAC learning because it breaks station roaming.
When enabled it drops all frames that arrive from a MAC address
that is on a different port at learning table.
