    mediatek: add support for ELECOM WRC-X3000GS3
    
    ELECOM WRC-X3000GS3 is a 2.4/5 GHz band 11ax (Wi-Fi 6) router, based on
    MT7981B.
    
    Specification:
    
    - SoC             : MediaTek MT7981B
    - RAM             : DDR3 512 MiB (Winbond W634GU6QB-09)
    - Flash           : SPI-NOR 128 MiB (Winbond W25N01GVZEIG)
    - WLAN            : 2.4/5 GHz 2T2R (MediaTek MT7981B (SoC))
    - Ethernet        : 5x 10/100/1000 Mbps
      - wan (phy)     : MediaTek MT7981B (SoC)
      - lan (switch)  : MediaTek MT7531A
    - LEDs/Keys (GPIO): 8x/4x
    - UART            : through-hole on PCB (J500)
      - assignment    : 3.3V, TX, RX, NC, GND from tri-angle marking
      - settings      : 115200n8
    - Power           : 12 VDC, 1 A (Max. 12.8 W)
    
    Flash instruction using factory.bin image:
    
    1. Boot WRC-X3000GS3 in router mode normally
    2. Access to the WebUI ("http://192.168.2.1/") on the device and open
       the firmware update page ("ファームウェア更新")
    3. Select the OpenWrt factory.bin image and click apply ("適用") button
    4. Wait ~120 seconds to complete flashing
    
    Switching to the stock firmware:
    
    1. Load the elecom.sh script
    
       . /lib/upgrade/elecom.sh
    
    2. Check the current index of firmware partition
    
       mstc_rw_bootnum
    
    3. Set the bootnum to opposite value between 1 and 2
    
       mstc_rw_bootnum <value>
    
       example:
    
       - step2 returned "1": mstc_rw_bootnum 2
    
       - step2 returned "2": mstc_rw_bootnum 1
    
    4. Reboot
    
    Notes:
    
    - ELECOM sells (or sold) multiple models as AX3000 class with different
      hardwares:
    
      - WRC-X3000GS(N) : Lantiq(Intel) GRX350/GRX550
      - WRC-X3000GS(T)2: Qualcomm IPQ5018
      - WRC-X3000GS3   : MediaTek MT7981B
    
    MAC Addresses:
    
    LAN   : 38:97:A4:xx:xx:40 (Factory, 0x2A(hex)/Ubootenv,"ethaddr"(text))
    WAN   : 38:97:A4:xx:xx:43 (Factory, 0x24(hex))
    2.4GHz: 38:97:A4:xx:xx:41 (Factory, 0x4 (hex))
    5GHz  : 38:97:A4:xx:xx:42 (Factory, 0xA (hex))
