Krzysztof Kozlowski 7366e19379 dt-bindings: PCI: qcom,pcie-ipq5018: Move IPQ5018 to dedicated schema
Move IPQ5018 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.
