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).

OpenWrt U-Boot layout flash instructions:
1. Flash stock layout firmware first.
2. Connect to the device via SSH, and backup everything,
especially 'Factory' partition.
3. Unlock MTD partitions:
apk update && apk add kmod-mtd-rw
insmod mtd-rw i_want_a_brick=1
4. Write new BL2 and FIP:
mtd write openwrt-mediatek-filogic-cmcc_a10-ubootmod-preloader.bin BL2
mtd write openwrt-mediatek-filogic-cmcc_a10-ubootmod-bl31-uboot.fip FIP
5. Set static IP on your PC:
IP 192.168.1.254/24, GW 192.168.1.1
6. Serve OpenWrt initramfs image using TFTP server.
7. Cut off the power and re-engage, wait for TFTP recovery to complete.
