drivers/perf: hisi_pcie: Add more events for counting TLP bandwidth

A typical PCIe transaction is consisted of various TLP packets in both
direction. For counting bandwidth only memory read events are exported
currently. Add memory write and completion counting events of both
direction to complete the bandwidth counting.
