Krzysztof Kozlowski 5e8bf1c1d5 dt-bindings: PCI: qcom,pcie-ipq9574: Move IPQ9574 to dedicated schema
Move IPQ9574 and compatible 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.
 - Make last "reg" entry "mhi" a required one, because all in-tree DTS
   were updated to include it.
