    ramips: add support for WAVLINK WL-WN577A2
    
    This commit adds support for the Wavlink WL-WN577A2 (black case) dual-band
    wall-plug wireless router. In Germany this device is sold under the brand
    name Maginon WL-755 (white case):
    
    Device specifications:
    
    - CPU: MediaTek MT7628AN (580MHz)
    - Flash: 8MB
    - RAM: 64MB
    - Bootloader: U-Boot
    - Ethernet: 2x 10/100 Mbps (Ralink RT3050)
    - 2.4 GHz: 802.11b/g/n SoC
    - 5 GHz: 802.11a/n/ac MT7610E
    - Antennas: internal
    - 4 green LEDs: 1 programmable (WPS) + LAN, WAN, POWER
    - Buttons: Reset, WPS
    - Small sliding power switch
    
    Flashing instructions (U-boot):
    
    - Configure a TFTP server on your PC/Laptop and set its IP
      to 192.168.10.100
    
    - Rename the OpenWrt image to firmware.bin and place it in the
      root folder of the TFTP server
    
    - Power off (using the small sliding power switch on the left
      side) the device and connect an ethernet cable from its LAN
      or WAN port to your PC/Laptop
    
    - Press the WPS button (and keep it pressed)
    
    - Power on the device (using the small power switch)
    
    - After a few seconds, when the WAN/LAN LED stops blinking
      very fast, release the WPS button
    
    - Flashing OpenWrt takes less than a minute, system will
      reboot automatically
    
    - After reboot the WPS LED will indicate the current OpenWrt
      running status
