mediatek: filogic: add support for TP-Link F65

Add support for TP-Link Festa F65, an AX3000 ceiling mount WiFi 6 AP.

Hardware
--------
SOC	: MediaTek MT7981B 2x A53
RAM	: ESMT M15T4G16256A 512MiB
Flash	: ESMT F50L1G41LB 128 MiB
ETH	: 1x 1GbE
WiFi	: MT7976
Buttons	: Reset
Leds	: Blue status led on top
Power	: DC 12V 1.2A / PoE

Installation
------------
1. Disassemble the device
2. Solder UART to pins VGRT right of the ethernet port
3. Connect UART console (3.3V)
4. Press Ctrl+b to stop in u-boot shell
5. Use `mtkload` to boot `openwrt-initramfs-kernel.bin` via tftp
6. Flash `openwrt-squashfs-sysupgrade.bin` via sysupgrade

Revert to OEM firmware
----------------------
1. Hold reset button while plugging in power
2. Configure host ethernet to 192.168.0.1/24
3. Go to http://192.168.0.254
4. Upload OEM firmware

MAC Addresses
-------------
LAN   : DC:62:79:xx:xx:28 (printed on label)
2.4GHz: DC:62:79:xx:xx:28
5GHz  : DC:62:79:xx:xx:29
