    ath79: add support for Ubiquiti PowerBridge M
    
    This adds support for the Ubiquiti PowerBridge M, which has the same
    board/LEDs as the Bullet M XM, but different case and antennas.
    
    Specifications:
    - AR7241 SoC @ 400 MHz
    - 64 MB RAM
    - 8 MB SPI flash
    - 1x 10/100 Mbps Ethernet, 24 Vdc PoE-in
    - Internal antenna: 25 dBi
    - POWER/LAN green LEDs
    - 4x RSSI LEDs (red, orange, green, green)
    - UART (115200 8N1) on PCB
    
    Flashing via WebUI:
    Upload the factory image via the stock firmware web UI.
    
    Attention: airOS firmware versions >= 5.6 have a new bootloader with
    an incompatible partition table!
    
    Please downgrade to <= 5.5 _before_ flashing OpenWrt!
    Refer to the device's Wiki page for further information.
    
    Flashing via TFTP:
    Same procedure as other Bullet M (XM) boards.
    
    - Use a pointy tool (e.g., pen cap, paper clip) and keep the reset
    button on the device or on the PoE supply pressed
    - Power on the device via PoE (keep reset button pressed)
    - Keep pressing until LEDs flash alternatively LED1+LED3 =>
    LED2+LED4 => LED1+LED3, etc.
    - Release reset button
    - The device starts a TFTP server at 192.168.1.20
    - Set a static IP on the computer (e.g., 192.168.1.21/24)
    - Upload via tftp the factory image:
    $ tftp 192.168.1.20
      tftp> bin
      tftp> trace
      tftp> put openwrt-ath79-generic-xxxxx-ubnt_powerbridge-m-squashfs-factory.bin
