Subject: [PATCH v3 2/6] dt-bindings: PCI: qcom,pcie-sm8450: move SM8450 to
dedicated schema
Move SM8450 PCIe devices from qcom,pcie.yaml binding to a dedicated file
to make reviewing easier.
This creates equivalent schema file, except:
- Missing required compatible which is actually redundant.
- Expecting eight MSI interrupts, instead of only one, which was
incomplete hardware description.
