[PATCH v3 0/2] arm64: dts: qcom: enable BT on SM8550-QRD

[Neil Armstrong]

This serie enables WCN7850 on the Qualcomm SM8550 QRD
reference platform.

The WCN7850 is close to the WCN6855 but uses different
firmware names.

This patchset is the followup of https://lore.kernel.org/r/20230620-topic-sm8550-upstream-bt-v2-0-98b0043d31a4@linaro.org
with only the DT patches.

---
Changes in v3:
- Dropped applied BT patches, on DT patches remains
- Link to v2: https://lore.kernel.org/r/20230620-topic-sm8550-upstream-bt-v2-0-98b0043d31a4@linaro.org

Changes in v2:
- Convert if/else and qca_is_*() macros by switch/case to simplify adding now BT SoCs
- Add bindings reviewed-by
- Link to v1: https://lore.kernel.org/r/20230620-topic-sm8550-upstream-bt-v1-0-4728564f8872@linaro.org
