coresight: etm4x: Fix enabling of cycle accurate tracing in perf.

Using perf record 'cyclacc' option in cs_etm event was not setting up cycle
accurate trace correctly.

Corrects bit set in TRCCONFIGR to enable cycle accurate trace.
Programs TRCCCCTLR with a valid threshold value as required by ETMv4 spec.
