perf cs-etm: Fix bitmap for option
When set option with macros ETM_OPT_CTXTID and ETM_OPT_TS, it wrongly
takes these two values (14 and 28 prespectively) as bit masks, but
actually both are the offset for bits. But this doesn't lead to
further failure due to the AND logic operation will be always true for
ETM_OPT_CTXTID / ETM_OPT_TS.
This patch defines new independent macros (rather than using the
"config" bits) for requesting the "contextid" and "timestamp" for
cs_etm_set_option().
