dt-bindings: PCI: qcom,pcie-ipq6018: Move IPQ6018 and IPQ8074 Gen3 to dedicated schema
Move IPQ6018 and IPQ8074 Gen3 (which is the same as in IPQ6018) PCIe devices from qcom,pcie.yaml binding to a dedicated file to make reviewing and maintenance easier. New schema is equivalent to the old one with few changes: - Adding a required compatible, which is actually redundant. - Drop the really obvious comments next to clock/reg/reset-names items. - Disallow legacy/incomplete description with only one interrupt and expect exactly nine of them. - Do not require power domains on IPQ6018, because old binding already does not require them for IPQ8074 Gen3, devices are the same and in-tree DTS lacks power domains.
