As the DT-bindings description states the Rockchip PCIe controller is
based on the DW PCIe RP IP-core thus its DT-nodes are supposed to be
compatible with the common DW PCIe controller schema. Let's make sure they
evaluated against it by referring to the snps,dw-pcie-common.yaml schema
in the allOf sub-schemas composition.

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Checked. No problem has been spotted:
