    ath79: remove wmac mtd-mac-address for UniFi AC family
    
    The MAC address for the wmac 2.4 GHz radio of the Ubiquiti UniFi AC
    family of devices is actually embedded in the mtd-cal-data, so there
    is no need for mtd-mac-address (which was incorrectly forcing wmac
    to have the same MAC as eth0). This makes it coherent with the stock
    firmware and the ar71xx target:
    
     · XX:XX:XX:X0:XX:XX eth0
     · XX:XX:XX:X1:XX:XX ath0/wlan1 (2.4 GHz)
     · XX:XX:XX:X2:XX:XX ath1/wlan0 (5 GHz)
    
    Checked on a UniFi AC Mesh, a UniFi AC LR and a UniFi Lite.
