    ramips: add support for ELECOM WRC-1750GS/GSV
    
    ELECOM WRC-1750GS is a 2.4/5 GHz band 11ac (Wi-Fi 5) router, based on
    MT7621A.
    
    WRC-1750GSV has the same hardware with WRC-1750GS.
    
    Specification:
    
    - SoC           : MediaTek MT7621A
    - RAM           : DDR3 128 MiB
    - Flash         : SPI-NOR 16 MiB
    - WLAN          : 2.4/5 GHz 3T3R (2x MediaTek MT7615)
    - Ethernet      : 10/100/1000 Mbps x5
      - Switch      : MediaTek MT7530 (SoC)
    - LED/keys      : 4x/6x (2x buttons, 1x slide-switch)
    - UART          : through-hole on PCB
      - J4: 3.3V, GND, TX, RX from ethernet port side
      - 57600n8
    - Power         : 12VDC, 1.5A
    
    Flash instruction using factory image:
    
    1. Boot WRC-1750GS (or WRC-1750GSV) normally
    2. Access to "http://192.168.2.1/" and open firmware update page
       ("ファームウェア更新")
    3. Select the OpenWrt factory image and click apply ("適用") button
       for WRC-1750GS : wrc-1750gs-squashfs-factory.bin
       for WRC-1750GSV: wrc-1750gsv-squashfs-factory.bin
    4. Wait ~120 seconds to complete flashing
