ar71xx: UBNT Secondary MAC address duplicate fix
There is Secondary MAC address duplicate problem with some UBNT
RouterStation and RouterStation Pro HW batches as Primary MAC addresses
are not increased by 2 per device in board data. Fix is to use 'Locally
Administrated bit' for Secondary MAC address instead of increasing
Primary MAC addresses by 1 which could overlap with other device
Primary MAC address.
