    ath79: add support for ZyXEL NWA1123-NI
    
    Specifications:
     * AR9342, 16 MiB Flash, 64 MiB RAM, 802.11n 2T2R, 2.4 GHz
     * AR9382 PCIe card, 802.11n 2T2R, 5 GHz
     * 1x Gigabit Ethernet (AR8035), 802.3af PoE
    
    Installation:
    * OEM Web UI is at 192.168.1.2
      login as `admin` with password `1234`
    * Flash factory-AAEO.bin
    
    The string `AAEO` needs to be present within the file name of the uploaded
    image to be accepted by the OEM Web-based updater, the factory image is
    named accordingly to save the user from the hassle of manual renaming.
    
    TFTP Recovery:
    * Open the case, connect to TTL UART port (this is the official method
      described by Zyxel, the reset button is useless during power-on)
    * Extract factory image (.tar.bz2), serve `vmlinux_mi124_f1e.lzma.uImage`
      and `mi124_f1e-jffs2` via tftp at 192.168.1.10
    * Interrupt uboot countdown, execute commands
      `run lk`
      `run lf`
      to flash the kernel / filesystem accordingly
    
    MAC addresses as verified by OEM firmware:
    use   address   source
    LAN   *:fb      mib0 0x30 ('eth0mac'), art 0x1002 (label)
    2g    *:fc      mib0 0x4b ('wifi0mac')
    5g    *:fd      mib0 0x66 ('wifi1mac')
