Move SC8180X 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.
