    ramips: add support for ELECOM WRC-2533GHBK2-T
    
    ELECOM WRC-2533GHBK2-T is a 2.4/5 GHz band 11ac (Wi-Fi 5) router, based
    on MT7621A.
    
    Specification:
    
    - SoC      : MediaTek MT7621A
    - RAM      : DDR3 128 MiB
    - Flash    : SPI-NOR 16 MiB (Macronix MX25L12835FM2I-10G)
    - WLAN     : 2.4/5 GHz 4T4R (2x MediaTek MT7615)
    - Ethernet : 10/100/1000 Mbps x5
      - Switch : MediaTek MT7530 (SoC)
    - LED/keys : 4x/3x (2x buttons, 1x slide-switch)
    - UART     : through-hole on PCB
      - J4: 3.3V, RX, GND, TX from SoC side
      - 57600n8
    - Power    : 12 VDC, 1.5 A
    
    Flash instruction using factory image:
    
    1. Boot WRC-2533GHBK2-T 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
    4. Wait ~150 seconds to complete flashing
    
    MAC addresses:
    
    LAN    : BC:5C:4C:xx:xx:FD (Config,  "ethaddr" (text))
    WAN    : BC:5C:4C:xx:xx:FC (Config,  "wanaddr" (text), Label)
    2.4 GHz: BC:5C:4C:xx:xx:FE (Factory, 0x4       (hex))
    5 GHz  : BC:5C:4C:xx:xx:FF (Factory, 0x8004    (hex))
