This patch adds support for OPP to vote for the performance state of RPMH
power domain based upon GEN speed it PCIe got enumerated.

Before link up PCIe driver will vote for the maximum performance state.

  dt-bindings: pci: qcom: Add binding for operating-points-v2
  arm64: dts: qcom: sm8450: Add opp table support to PCIe
  PCI: qcom: Add OPP suuport for speed based performance state of RPMH
