    realtek: add support for I-O DATA BSH-G24MB
    
    I-O DATA BSH-G24MB is a 24 port gigabit switch, based on RTL8382M.
    
    Specification:
    
    - SoC           : Realtek RTL8382M
    - RAM           : DDR2 128 MiB (Nanya NT5TU128M8HE-AC)
    - Flash         : SPI-NOR 16 MiB (Macronix MX25L12835FM2I-10G)
    - Ethernet      : 10/100/1000 Mbps x24
      - port 1-8    : RTL8218B
      - port 9-16   : RTL8218B (SoC)
      - port 17-24  : RTL8218B
    - LEDs/Keys     : 2x, 1x
    - UART          : pin header on PCB
      - JP2: 3.3V, TX, RX, GND from rear side
      - 115200n8
    - Power         : 100 VAC, 50/60 Hz
      - Plug        : IEC 60320-C13
    
    Flash instruction using sysupgrade image:
    
    1. Boot BSH-G24MB normally
    2. Connect BSH-G24MB to the DHCP enabled network
    3. Find the device's IP address and open the WebUI and login
       Note: by default, the device obtains IP address from DHCP server of
             the network
    4. Open firmware update page ("ファームウェア アップデート")
    5. Rename the OpenWrt sysupgrade image to "bsh-g24mb_v100.image" and
       select it
    6. Press apply ("適用") button to perform update
    7. Wait ~150 seconds to complete flashing
    
    Note:
    
    - BSH-G24MB has a power-related LED ("電源"), but it's not connected to
      the GPIO of the SoC or RTL8231 and cannot be controlled. Instead of
      it, use system status LED on other than running-state.
    
    - "sys_loop" LED indicates system status and loop-detection status in
      stock firmware.
    
    - BSH-G24MB has 2x os-image partitions named as "RUNTIME"/"RUNTIME2" in
      16 MiB SPI-NOR flash and the size of image per partition is only
      6848 KiB. The secondary image is never used on stock firmware, so also
      use it on OpenWrt to get more space.
