Hello,

intel_pstate_tracer is a useful tool to analyze the performance of
intel_pstate driver. We upstream out AMD P-state driver into Linux
kernel recently and like to use similar tool to tune the performance
of the driver.

I modified intel_pstate_tracer.py then it could import as a module to
analyze AMD P-State trace event. Other trace event also can benifit from
this change once they need this tool.

intel_pstate_tracer could be used as the same way as before and the
original functionality isn't broken.

Changes from V2->V3

-fix typo in amd-pstate RST

Changes from V1->V2

-Add tracer documentation in amd-pstate RST

-fix typo in amd_pstate_trace.py

-add "Co-developed-by" in patch 1/4

Thanks,
Joe
