    bmips: add support for Comtrend AR-5381u
    
    The Comtrend AR-5381u is a wifi fast ethernet router, 2.4 GHz single band with
    two internal antennas.
    
    Hardware:
     - SoC: Broadcom BCM6328
     - CPU: single core BMIPS4350 @ 320Mhz
     - RAM: 64 MB DDR
     - Flash: 16 MB SPI NOR
     - Ethernet LAN: 4x 100Mbit
     - Wifi 2.4 GHz: miniPCI Broadcom BCM43225 802.11bgn
     - USB: 1x 2.0
     - Buttons: 1x (reset)
     - LEDs: yes
     - UART: yes
    
    Installation via CFE web UI:
      1. Power off the router.
      2. Press reset button near the power switch.
      3. Keep it pressed while powering up during ~20+ seconds.
      4. Browse to http://192.168.1.1 and upload the firmware.
      5. Wait a few minutes for it to finish.
