mediatek: filogic: ASUS RT-AX52 PRO support

Browse Source 
The board is exactly identical to the ASUS RT-AX52, I've literally not changed a single thing.
Only AX52 is AX1800, PRO is AX3000.

SOC: MediaTek MT7981b
RAM: 256MB DDR3
FLASH: 128MB SPI-NAND (Winbond W25N01GV)
WIFI: Mediatek MT7981b DBDC 802.11ax 2.4/5 GHz
ETH: MediaTek MT7531 Switch
UART: 3V3 115200 8N1 (Pinout silkscreened / Do not ocnnect VCC)

Use the compiled asus_rt-ax52-pro-initramfs.trx file from the this repo.

Connect the PC via LAN to one of the yellow router ports and wait until your PC to get a DHCP lease.

Browse to http://192.168.50.1 or http://www.asusrouter.com/

If your router is brand new, finish the setup process and log into the Web-UI.

Navigate to Administration → Firmware Upgrade or use this link http://www.asusrouter.com/Advanced_FirmwareUpgrade_Content.asp.

Upload the .trx file to router

Wait for it to reboot

trx image is initramfs version. You must upgrade to squashfs version.

Browse to http://192.168.1.1/cgi-bin/luci/admin/system/flash

Upload asus_rt-ax52-pro-squashfs-sysupgrade.bin and use sysupgrade -n

Wait for it to reboot

SSH to 192.168.1.1 and set a root password, or browse to http://192.168.1.1

-------Revert to stock asus firmware ---------:
1: Download the rt-ax52 firmware from ASUS official website. Save the firmware to tftp server directory and rename to RT-AX52.trx

2: Connect the PC with TFTP server to the RT-AX52. Set a static ip on the ethernet interface of your PC. (ip address: 192.168.1.70, subnet mask:255.255.255.0)

3: Conect to the serial console, power on again, interrupt the autoboot process by pressing '4' when prompted. $ ubi remove linux
$ ubi remove jffs2
$ ubi remove rootfs
$ ubi remove rootfs_data
$ ubi create linux 0x45fe000
$ reset
then the dut will reboot,interrupt the autoboot process by pressing '2' when prompted. 2: Load System code then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N) $: enter y
you will see the follow, type enter directly:
Input device IP (192.168.1.1) ==:
Input server IP (192.168.1.70) ==:
Input Linux Kernel filename (RT-AX52.trx) ==:

4: wait for the device run up
