"Microsoft Windows Dev Kit 2023" aka "Blackrock" aka "Project Volterra"

Device tree for the Microsoft Windows Dev Kit 2023. This work
is based on the initial work of Merck Hung <merckhung@gmail.com>.

The Windows Dev Kit 2023 is a nice little desktop based on sc8280xp.
Link: https://learn.microsoft.com/en-us/windows/arm/dev-kit/

Supported features:
- USB type-c and type-a ports
- minidp connector
- built-in r8152 Ethernet adapter
- PCIe devices
- nvme
- ath11k WiFi (WCN6855)
- WCN6855 Bluetooth
- A690 GPU
- Venus codec
- ADSP and CDSP
- GPIO keys
- Audio definition (works via USB)

Original work: https://github.com/merckhung/linux_ms_dev_kit/blob/ms-dev-kit-2023-v6.3.0/arch/arm64/boot/dts/qcom/sc8280xp-microsoft-dev-kit-2023.dts

This dt is more or less deducted from the Thinkpad X13s.
It contains a lot of guesswork, and also a lot of research on
what works with the Windows Dev Kit.

The WiFi definition references qcom,ath11k-calibration-variant = "volterra"
which is unfortunately not yet in the linux-firmware. You can leave it out,
and the ath11k driver finds the default one for 
"bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2|18,qmi-board-id=255"
which is quite sub-optimal. I have placed a pr on github/qca-swiss-army-knife:
https://github.com/qca/qca-swiss-army-knife/pull/9 that provides an amended 
board-2.bin and a board-2.json to generate it. 

pcie2 (nvme) is intentionally specified as max-link-speed = <16>. The 
interface is capable of it, most current nvme ssds are capable of it, 
but the physical slot isn't. This leads to a silent downgrade to <8> instead 
of the "device is limited by bus, capable of..." message.

It is in use and under development since May 2023, pretty stable now.

- amended indentation
- consistently used blackrock as identifier / directory name
- sorted identifiers by the same order for multiple instances
- added some explanation re WiFi
- added definition for PMU on the WCN6855
- added some explanation for pcie2 max-link-speed
- Link to v2: https://lore.kernel.org/r/20240920-jg-blackrock-for-upstream-v2-0-9bf2f1b2191c@oldschoolsolutions.biz

Changes in v2:
- removed whitespaces and breaks
- added compatibility binding
- added feature list
- reformatted Signed-off list
- Link to v1: https://lore.kernel.org/r/5f5487e1-e458-4a3a-af02-c52e50ca1964@oldschoolsolutions.biz

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
