    ramips: add support for ELECOM WMC-M1267GST2
    
    ELECOM WMC-M1267GST2 is a 2.4/5 GHz band 11ac (Wi-Fi 5) mesh router,
    based on MT7621A.
    
    Specification:
    
    - SoC          : MediaTek MT7621A
    - RAM          : DDR3 256 MiB (Nanya NT5CC128M16JR-EK)
    - Flash        : SPI-NOR 32 MiB (Winbond W25Q256JVFIQ)
    - WLAN         : 2.4/5 GHz 2T2R (MediaTek MT7615D)
    - Ethernet     : 10/100/1000 Mbps x5
      - switch     : MediaTek MT7530 (SoC)
    - LEDs/Keys    : 6x/6x
    - UART         : through-hole on PCB ("J4")
      - arrangement: 3.3V, GND, TX, RX from tri-angle marking
      - settings   : 57600n8
    - Power        : 12 VDC, 1 A
    
    Flash instruction using factory image:
    
    1. Boot WMC-M1267GST2 normally with "Router" mode
    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
    4. Wait ~120 seconds to complete flashing
    
    MAC addresses:
    
    LAN    : 04:AB:18:xx:xx:61 (Factory, 0xFFF4 (hex))
    WAN    : 04:AB:18:xx:xx:62 (Factory, 0xFFFA (hex))
    2.4 GHz: 04:AB:18:xx:xx:63
    5 GHz  : 04:AB:18:xx:xx:64 (Factory, 0x4 (hex))
