arm64: dts: meson: add support for the WeTek Core 2
The WeTek Core2 is a commercial device based on the Amlogic Q200 reference
design but with the following differences:
- 3GB RAM, 32GB eMMC
- Blue and Red LEDs used to signal on/off status
- uart_AO can be accessed after opening the case; soldering required
- USB OTG is not accessible (inside the case)
- Realtek RTL8152 Ethernet (internal USB connection)
