Upstream uses a different filename, so lets rename our downstream
mt7981.dtsi to mt7981b.dtsi and update the device tree of all
MT7981 boards accordingly.
This is to prepare for the switch to Linux 6.12 which is going to
use the upstream mt7981b.dtsi (plus some patches on top).

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.
