Leo Yan 26218331f4 perf auxtrace: Add 'T' itrace option for timestamp trace 
An AUX trace can contain timestamp, but in some situations, the hardware
trace module (e.g. Arm CoreSight) cannot decide the traced timestamp is
the same source with CPU's time, thus the decoder can not use the
timestamp trace for samples.

This patch introduces 'T' itrace option. If users know the platforms
they are working on have the same time counter with CPUs, users can
use this new option to tell a decoder for using timestamp trace as
kernel time.
