    ramips: add support for TP-Link TL-WR902AC v3
    
    TP-Link TL-WR902AC v3 is a pocket-size dual-band (AC750) router
    based on MediaTek MT7628N + MT7650E.
    
    Specification:
    - MediaTek MT7628N/N (580 Mhz)
    - 64 MB of RAM
    - 8 MB of FLASH
    - 2T2R 2.4 GHz and 1T1R 5 GHz
    - 1x 10/100 Mbps Ethernet
    
    * MT7650 ac chip isn't not supported by LEDE/OpenWrt at the moment.
      Therefore 5Ghz won' work.
    
    Flash instruction:
    
    The only way to flash LEDE image in TL-WR902AC v3 is to use
    tftp recovery mode in U-Boot:
    
    1. Configure PC with static IP 192.168.0.66/24 and tftp server.
    2. Rename "openwrt-ramips-mt76x8-tplink_tl-wr902ac-v3-squashfs-tftp-recovery.bin"
       to "tp_recovery.bin" and place it in tftp server directory.
    3. Connect PC with the LAN port, press the reset button, power up
       the router and keep button pressed for around 6-7 seconds, until
       device starts downloading the file.
    4. Router will download file from server, write it to flash and reboot.
