[PATCH 4/4] arm64: dts: qcom: Add support for X1-based Surface Laptop 7 devices

From: Konrad Dybcio <quic_kdybcio@quicinc.com>

Add support for Surface Laptop 7 machines, based on X1E80100.

The feature status is mostly on par with other X Elite machines,
notably lacking:

- USB-A and probably USB-over-Surface-connector
- SD card reader (Realtek RTS5261 connected over PCIe)
- Touchscreen and touchpad support (hid-over-SPI [1])
- Keyboard support (low-hanging fruit, works with pending Surface EC
changes)
- Audio (a quick look suggests the setup is very close to the one in
X1E CRD)

The two Surface Laptop 7 SKUs (13.8" and 15") only have very minor
differences, amounting close to none on the software side. Even the
MBN firmware files and ACPI tables are shared between the two machines.

With that in mind, support is added for both, although only the larger
one was physically tested. Display differences will be taken care of
through fused-in EDID and other matters should be solved within the
EC and boot firmware.
