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.
Changes since v1: - Drop the internal Reviewed-by tag. - Fix some build warnings when W=1.
