dt-bindings: PCI: qcom,pcie-sm8150: Move SM8150 to dedicated schema
Move SM8150 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.
