    ramips: add support for ALFA Network AWUSFREE1
    
    ALFA Network AWUSFREE1 is an USB Wi-Fi N300 adapter based on MT7628.
    
    Specification:
    
    - MT7628AN (580 MHz)
    - 64 MB of RAM (DDR2)
    - 8 MB of FLASH (SPI NOR)
    - 2T2R 2.4 GHz (MT7628) with external FEM (RFFM4203)
    - 2x detachable antennas (RP-SMA)
    - ASIX AX88772 USB to Ethernet bridge (connected with MT7628 PHY0)
    - 4x LED (2 driven by GPIO)
    - 1x button (reset)
    - 1x mini USB for host and main power input
    - UART header on PCB
    
    Flash instruction:
    
    You can use sysupgrade image directly in vendor firmware which is based
    on LEDE/OpenWrt. Alternatively, you can use web recovery mode in U-Boot:
    
    1. Power device with reset button pressed and release it after ~5 sec.
    2. Setup static IP 192.168.1.2/4 on your PC.
    3. Go to 192.168.1.1 in browser and upload "sysupgrade" image.
