arm64: dts: qcom: sc8280xp: Add Microsoft Surface Pro 9 5G

Add an initial devicetree for the Microsoft Surface Pro 9 5G, based
on SC8280XP.

It enables the support for Wi-Fi, NVMe, the two USB Type-C ports,
Bluetooth, 5G cellular modem, audio output (via Bluetooth headsets
or USB audio), external display via DisplayPort over Type-C (only
the bottom USB Type-C port is working so far), charging, the Surface
Aggregator Module (SAM) to get keyboard and touchpad working with
Surface Type Cover accessories.

Some key features not supported yet:
- built-in display (but software fallback is working with efifb
  when blacklisting the msm module)
- built-in display touchscreen
- external display with the top USB Type-C port
- speakers and microphones
- physical volume up and down keys
- LID switch detection

This devicetree is based on the other SC8280XP ones, for the Lenovo
ThinkPad X13s and the Qualcomm CRD.
