    mediatek: add support for device zbt-z8103ax-c
    
    - adopted MTD partition size increase from 64M to 128M
      -> this allows boot to complete
    - moved MAC addressing stuff out of partition definitions
    - all MAC addressing stuff is in .dtsi
    
    Specifications:
    
    SoC: MediaTek MT7981B
    RAM: 256MiB
    Flash: Winbond SPI-NAND 128 MiB
    Switch: 1 WAN, 3 LAN (Gigabit) MediaTek MT7531
    Buttons: Reset, Mesh
    Power: DC 12V 1A
    WiFi: MT7981B 2.4Ghz & 5.8Ghz
    
    Led Layout from bottom to top:
    
        Power
        Mesh (RGB Led, user controllable, default set to OpenWrt Status)
        WLAN 2 GHz (user controllable)
        WAN (user controllable)
        LAN3
        LAN2
        LAN1
        WLAN 5 GHz (Not on front panel but blinks through enclosure,
                   user controllable)
    
    Buttons:
    
        Reset
        Mesh (user controllable, no default function)
    
    Installation:
    
    A. Through U-Boot menu:
    
     -  Prepare your connecting computer to use a static IP in
            network 192.168.1.0/24
     -  Power down the router and hold in the Reset button.
     -  While holding in the button power up the router again.
     -  Hold the button in for 10 seconds and then release.
     -  Use your browser to go to 192.168.1.1
     -  If you see a GUI allowing for flashing firmware then
            you got the right model.
     -  Upload the sysupgrade file.
    
    Note: Recovery GUI can be used to recover from an incorrect
          firmware flash.
    
    B. Through OpenWrt Dashboard:
    
        If your router comes with OpenWrt preinstalled
            (modified by the seller), you can easily upgrade
            by going to the dashboard (192.168.1.1) and then
            navigate to System -> Backup/Flash firmware,
            then flash the firmware
    
    MAC Addresses were found in Factory partition:
    
    offset 0x4 F8:5E:3C:xx:xx:aa --> Router Label -2
    offset 0xa F8:5E:3C:xx:xx:bb --> Router Label -1
    offset 0x24 F8:5E:3C:xx:xx:cc --> Router Label +1
    offset 0x2a F8:5E:3C:xx:xx:yy --> printed on Router Label
