    mediatek: add Xiaomi Redmi Router AX6000 support
    
    Hardware specification:
      SoC: MediaTek MT7986A 4x A53
      Flash: ESMT F50L1G41LB 128 MB
      RAM: K4A4G165WF-BCWE 512 MB
      Ethernet: 4x 10/100/1000 Mbps
      WiFi1: MT7976GN 2.4GHz ax 4x4
      WiFi2: MT7976AN 5GHz ax 4x4
      Button: Mesh, Reset
    
    Flash instructions:
      1. Gain ssh and serial port access, see the link below:
         https://openwrt.org/toh/xiaomi/redmi_ax6000#installation
      2. Use ssh or serial port to log in to the router, and
         execute the following command:
         nvram set boot_wait=on
         nvram set flag_boot_rootfs=0
         nvram set flag_boot_success=1
         nvram set flag_last_success=1
         nvram set flag_try_sys1_failed=8
         nvram set flag_try_sys2_failed=8
         nvram commit
      3. Set a static ip on the ethernet interface of your computer
         (e.g. default: ip 192.168.31.100, gateway 192.168.31.1)
      4. Download the initramfs image, rename it to initramfs.bin,
         and host it with the tftp server.
      5. Interrupt U-Boot and run these commands:
         setenv mtdparts nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),2048k(factory),2048k(fip),256k(crash),256k(crash_log),112640k(ubi)
         saveenv
         tftpboot initramfs.bin
         bootm
      6. After openwrt boots up, use scp or luci web
         to upload sysupgrade.bin to upgrade.
    
    Revert to stock firmware:
      Restore mtdparts back to default, then use the
      vendor's recovery tool (Windows only).
