Qi Liu 5e91e57e68 perf auxtrace arm64: Add support for parsing HiSilicon PCIe Trace packet 
Add support for using 'perf report --dump-raw-trace' to parse PTT packet.

Example usage:

Output will contain raw PTT data and its textual representation, such
as (8DW format):

0 0 0x5810 [0x30]: PERF_RECORD_AUXTRACE size: 0x400000  offset: 0
ref: 0xa5d50c725  idx: 0  tid: -1  cpu: 0
.
. ... HISI PTT data: size 4194304 bytes
.  00000000: 00 00 00 00                                 Prefix
.  00000004: 08 20 00 60                                 Header DW0
.  00000008: ff 02 00 01                                 Header DW1
.  0000000c: 20 08 00 00                                 Header DW2
.  00000010: 10 e7 44 ab                                 Header DW3
.  00000014: 2a a8 1e 01                                 Time
.  00000020: 00 00 00 00                                 Prefix

....

This patch only add basic parsing support according to the definition of
the PTT packet described in Documentation/trace/hisi-ptt.rst. And the
fields of each packet can be further decoded following the PCIe Spec's
definition of TLP packet.
