Add the missing "device_type" property to fix the memory node. The
Linux kernel can not get the memory size without it. Though u-boot
can automatically fixup the memory node by adding the "device_type"
and "reg" properties if the CONFIG_ARCH_FIXUP_FDT_MEMORY symbol is
enabled, it's better not to rely on this optional feature. This
patch also adds the reg address for the memory node name to follow
the naming rules.

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 OpenWrt U-Boot layout support for Routerich AX3000. The
aims:
1. Get open-source U-Boot;
2. Get maximum available free space in OpenWrt.
Install
-------
1. Copy OpenWrt ubootmod-bl31-uboot.fip, ubootmod-preloader.bin, to the
/tmp folder of the router using scp.
2. Make mtd partitions backups:
http://192.168.1.1/cgi-bin/luci/admin/system/flash -> Save mtdblock
contents
3. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
4. Write FIP and preloader:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd erase BL2
mtd write /tmp/ubootmod-preloader.bin BL2
mtd unlock FIP
mtd erase FIP
mtd write /tmp/ubootmod-bl31-uboot.fip FIP
```
5. Copy OpenWrt ubootmod-initramfs-recovery.itb to the tftp server root
with IP 192.168.1.254.
6. Reboot router:
```
reboot
```
U-Boot will automatically download from the tftp server and boot OpenWrt
initramfs system.
7. Copy OpenWrt ubootmod-squashfs-sysupgrade.itb to the /tmp dir of the
router using scp.
8. Run sysupgrade:
```
sysupgrade -n /tmp/squashfs-sysupgrade.itb
```
Recovery
--------
1. Place OpenWrt initramfs-recovery.itb image (with original name) on the
tftp server (IP: 192.168.1.254).
2. Press "reset" button and power on the router. After ~10 sec release the
button.
3. Use OpenWrt initramfs system for recovery.
BL2 and FIP recovery
--------------------
Use mtk_uartboot and UART connection if BL2 or FIP in UBI is destroyed:

Return to stock:
----------------
1. Copy partition backups (BL2.bin and FIP.bin) to the /tmp dir of the
router using scp.
2. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
3. Restore stock U-Boot and reboot:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd erase BL2
mtd write /tmp/BL2.bin BL2
mtd unlock FIP
mtd erase FIP
mtd write /tmp/FIP.bin FIP
reboot
```
4. Open U-Boot web recovery, upload stock firmware image and start
upgrade.
