    filogic: add support for ASUS TUF-AX4200
    
    Hardware
    --------
    SOC:   MediaTek MT7986
    RAM:   512MB DDR3
    FLASH: 256MB SPI-NAND (Winbond W25N02KV)
    WIFI:  Mediatek MT7986 DBDC 802.11ax 2.4/5 GHz
    ETH:   MediaTek MT7531 Switch
           MaxLinear GPY211C 2.5 N-Base-T PHY
    UART:  3V3 115200 8N1 (Pinout silkscreened / Do not ocnnect VCC)
    
    Installation
    ------------
    
    1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
       reachable at 192.168.1.66/24. Rename the image to tufax4200.bin.
    
    2. Connect the TFTP server to the AX4200. Conect to the serial console,
       interrupt the autoboot process by pressing '4' when prompted.
    
    3. Download & Boot the OpenWrt initramfs image.
    
       $ setenv ipaddr 192.168.1.1
       $ setenv serverip 192.168.1.66
       $ tftpboot 0x46000000 tufax4200.bin
       $ bootm 0x46000000
    
    4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
       using scp and install using sysupgrade.
    
       $ sysupgrade -n <path-to-sysupgrade.bin>
    
    Missing features
    ----------------
    
     - The LAN port LEDs are driven by the switch but OpenWrt does not
       correctly configure the output.
