Subject: [PATCH 90/91] perf cs-etm: Move definition of 'traceid_list' global variable from header file

From: Leo Yan <leo.yan@...aro.org>

The variable 'traceid_list' is defined in the header file cs-etm.h,
if multiple C files include cs-etm.h the compiler might complaint for
multiple definition of 'traceid_list'.

To fix multiple definition error, move the definition of 'traceid_list'
into cs-etm.c.

Fixes: cd8bfd8c973e ("perf tools: Add processing of coresight metadata")
