    ramips: add support for Asus RT-AC51U
    
    Specification:
     - SoC: MediaTek MT7620A (580 MHz)
     - RAM: 64 MiB (Winbond W9751G6JB-25)
     - Flash: 16 MiB (Spansion S25FL128SAIF00)
     - LAN: x4 100M
     - WAN: x1 100M
     - Others: USB 2.0, reset button, wps button and 9 LEDs
    
    Issues:
     - 5 GHz band is not functional (missing driver support)
    
    Installation:
    
    Asus windows recovery tool:
     - install the Asus firmware restoration utility
     - unplug the router, hold the reset button while powering it on
     - release when the power LED flashes slowly
     - specify a static IP on your computer:
         IP address: 192.168.1.75;
         Subnet mask 255.255.255.0
     - Start the Asus firmware restoration utility, specify the sysupgrade
       image, and press upload
    
    TFTP Recovery method:
     - set computer to a static ip, 192.168.1.75
     - connect computer to the LAN 1 port of the router
     - hold the reset button while powering on the router for a few seconds
     - send firmware image using a tftp client; i.e from linux:
     $ tftp
     tftp> binary
     tftp> connect 192.168.1.1
     tftp> put lede-ramips-mt7620-rt-ac51u-squashfs-sysupgrade.bin
     tftp> quit
