ramips: add support for wavlink halo base pro

This adds support for the Wavlink "Halo Base Pro".
SOC: MT7621DAT
RAM: 128MiB
Flash: 16MiB NOR
WiFi: MT7603EN + MT7613BEN

Buttons:
- The touch sensor was originally for WPS, but this has been moved to the
pair button which is no longer used to prevent accidental touches

LEDs:
- On original firmware, the status LEDs light up as follows:
- Purple = booting, Blue = working, Red = error

Partitions:
- factory contains unique WiFi EEPROM and default MAC addresses
- vendor partition has an unknown purpose

Stock MAC address allocation:
- LAN1:				xx:xx:xx:xx:xx:80
- LAN2/WAN:		xx:xx:xx:xx:xx:81
- WiFi 2.4G:	xx:xx:xx:xx:xx:82
- WiFi 5G:		xx:xx:xx:xx:xx:83

LAN Ports:
- lan1 is the normal white LAN port
- lan2 is labelled "LAN/Backhaul", which can either be LAN or WAN.
	- Since this device is intended to be part of a mesh, this will usually
		be a LAN port, hence why it's assigned to lan2 here

Notes:
- I've chosen "Halo Base Pro" as the device model, despite the website URL
showing WL-WN535M3, as the label only states "Halo Base Pro".
- Only the 5GHz WiFi address is labelled on the device
