arm64: dts: qcom: sm8450: Add OPP table support to PCIe

Browse source

PCIe host controller driver needs to choose the appropriate performance
state of RPMh power domain and interconnect bandwidth based on the PCIe
data rate.

Hence, add the OPP table support to specify RPMh performance states and
interconnect peak bandwidth.

It should be noted that the different link configurations may share the
same aggregate bandwidth, e.g., a 2.5 GT/s x2 link and a 5.0 GT/s x1
link have the same bandwidth and share the same OPP entry.
