    ramips: fix Tenbay T-MB5EU v1 Wireless MAC
    
    It was reported, that Tenbay T-MB5EU v1 do have incorrect Wireless MAC
    address set on 2.4 and 5 GHz.
    
    Some boards do not seem to have the correct MAC address set for the
    external PHY of the MT7915 radio at caldata offset 0xa.
    
    As the external PHY does not expose a DT binding (yet), fix up the mac
    address in userspace.
