    ramips: fix Ethernet random MAC address for HILINK HLK-7628N
    
    Set the ethernet address from flash.
    
    MAC addresses as verified by OEM firmware:
    
      use   interface  source
      2g    wlan0      factory 0x04 (label)
      LAN   eth0.1     factory 0x28 (label+1)
      WAN   eth0.2     factory 0x2e (label+2)
