dt-bindings: PCI: qcom: Move OPP table to qcom,pcie-common.yaml

OPP table is a generic property that is also required by other Qcom
platforms.

Hence move this property to qcom,pcie-common.yaml so that PCIe on other
Qcom platforms is able to adjust power domain performance state and ICC
peak bandwidth according to the given PCIe generation speed and link
width.
