perf auxtrace arm64: Add support for HiSilicon PCIe Tune and Trace device driver

HiSilicon PCIe tune and trace device (PTT) could dynamically tune the
PCIe link's events, and trace the TLP headers).

This patch add support for PTT device in perf tool, so users could use
'perf record' to get TLP headers trace data.
