perf cs-etm: Add fix for coresight trace for any range of CPUs

The current implementation supports coresight trace decode for a range
of CPUs, if the first CPU is CPU0.

Perf report segfaults, if tried for sparse CPUs list and also for
any range of CPUs(non zero first CPU).

Adding a fix to perf report for any range of CPUs and for sparse list.
