    ath79: add support for Ubiquiti airCube AC
    
    The Ubiquiti Network airCube AC is a cube shaped device supporting
    2.4 GHz and 5 GHz with internal 2x2 MIMO antennas.
    It can be powered with either one of:
     - 24v power supply with 3.0mm x 1.0mm barrel plug
     - 24v passive PoE on first LAN port
    There are four 10/100/1000 Mbps ports (1 * WAN + 3 * LAN).
    First LAN port have optional PoE passthrough to the WAN port.
    
    SoC:       Qualcomm / Atheros AR9342
    RAM:       64 MB DDR2
    Flash:     16 MB SPI NOR
    Ethernet:  4x 10/100/1000 Mbps (1 WAN + 3 LAN)
    LEDS:      1x via a SPI controller (not yet supported)
    Buttons:   1x Reset
    Serial:    1x (only RX and TX); 115200 baud, 8N1
    
    Missing features:
     - LED control is not supported
    
    Physical to internal switch port mapping:
     - physical port #1 (poe in) = switchport 2
     - physical port #2 = switchport 3
     - physical port #3 = switchport 5
     - physical port #4 (wan/poe out) = switchport 4
    
    Factory update is tested and is the same as for Ubiquiti AirCube ISP
    hence the shared configuration between that devices.
