Subject: [PATCH v7 4/7] dt-bindings: pci: qcom: Add opp table

PCIe needs to choose the appropriate performance state of RPMH power
domain based upon the PCIe gen speed.

Adding the Operating Performance Points table allows to adjust power
domain performance state and icc peak bw, depending on the PCIe gen
speed and width.
