[PATCH 6/6] arm64: dts: qcom: sc8280xp: add Radxa Dragon Q8B

[Xilin Wu <sophon@radxa.com>]

Add initial device tree support for the Radxa Dragon Q8B,
a single-board computer based on the Qualcomm Snapdragon 8cx Gen 3
SC8280XP platform.

Describe the following hardware:

- UFS and microSD storage
- Two M.2 M-key PCIe connectors
- An M.2 E-key connector for Wi-Fi and Bluetooth
- The QPS615 PCIe switch and its downstream topology
- Two USB-C ports with DisplayPort alternate mode
- USB Type-A ports
- HDMI 2.1 output through the Chrontel CH7218A bridge
- WCD9385 headset audio
- GPU, video, ADSP and CDSP remote processors
- RTC, EEPROM, thermal sensors and the 40-pin expansion header
