Subject: [PATCH 29/63] perf cs-etm: Refactor enumeration cs_etm_sample_type

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

The values in enumeration cs_etm_sample_type are defined with setting
bit N for each packet type, this is not suggested in the usual case.

This patch refactor cs_etm_sample_type by converting from bit shifting
values to continuous numbers.
