Subject: [PATCH 2/2] arm64: dts: meson: add initial device-tree for Minix NEO U9-H

Minix NEO U9-H is based on the Amlogic Q200 reference board with an
S912-H chip and the following specs:

- 2GB DDR3 RAM
- 16GB eMMC
- 10/100/1000 Base-T Ethernet
- AP6356S Wireless (802.11 a/b/g/n/ac, BT 4.1)
- RTC chip
- HDMI 2.1 video
- S/PDIF optical output
- ES8323 audio codec
- Analogue headphone output
- 3x USB 2.0 ports (1x OTG)
- IR receiver
- 1x Power LED (white)
- 1x Power button (rear)
- 1x Update/Reset button (underside)
- 1x micro SD card slot
