This patchset adds support for HiSilicon PCIe Performance Monitoring
Unit(PMU). It is a PCIe Root Complex integrated End Point(RCiEP) device
added on Hip09. Each PCIe Core has a PMU RCiEP to monitor multi root
ports and all Endpoints downstream these root ports.

HiSilicon PCIe PMU is supported to collect performance data of PCIe bus,
such as: bandwidth, latency etc.
