mediatek: add support for Mercusys MR80X v3
This commit adds support for Mercusys MR80X(EU) v3 router.

Device specification:
 - SoC: Mediatek MT7981b, Cortex-A53, 64-bit
 - RAM: 512MB
 - Flash: SPI NAND GigaDevice GD5F1GQ5UEYIGY (128 MB)
 - Ethernet: 4x 100/1000 Mbps LAN1,LAN2,LAN3 & WAN
 - Wireless: 2.4GHz (802.11 b/g/n/ax)
 - Wireless: 5GHz (802.11 a/n/ac/ax)
 - LEDs: 1 orange and 1 green status LEDs, 4 green gpio-controlled LEDs
   on ethernet ports
 - Buttons: 1 (Reset)
 - Bootloader: Main U-Boot - U-Boot 2022.01-rc4. Additionally, both UBI
   slots contain "seconduboot" (also U-Boot 2022.01-rc4)

Installation (UART):
 - Place OpenWrt initramfs-kernel image on tftp server with IP 192.168.1.2
 - Attach UART, switch on the router and interrupt the boot process by
   pressing 'Ctrl-C'.
 - Set the uboot environment for startup.
   setenv tp_boot_idx 0; setenv bootcmd bootm 0x46000000; saveenv
   If the bootarg is set to boot from ubi1, also change it to ubi0.
 - Load and run OpenWrt initramfs image.
   setenv serverip 192.168.1.2; setenv ipaddr 192.168.1.1; tftpboot initramfs-kernel.bin; bootm
 - Browse IP 192.168.1.1, upload the 'sysupgrade' image and do upgrade.

Recovery:
 - Press Reset button and power on the router.
 - Navigate to U-Boot recovery web server (http://192.168.1.1/) and
   upload the OEM firmware.
