Subject: [PATCH 4/4] arm64: dts: meson-g12b-gtking-pro: add initial device-tree

The Shenzen AZW (Beelink) GT-King Pro is based on the Amlogic W400 reference
board with an S922X chip.

- 4GB LPDDR4 RAM
- 64GB eMMC storage
- 10/100/1000 Base-T Ethernet
- AP6356S Wireless (802.11 a/b/g/n/ac, BT 4.1)
- HDMI 2.1 video
- Analogue audio output
- 1x RS232 port
- 2x USB 2.0 port
- 2x USB 3.0 ports
- IR receiver
- 1x full-size (not micro) SD card slot
- 1x Power on/off button

The rear RS232 port is not currently supported in the device-tree.
