perf: cs-etm: Fix ETMv4 CONFIGR entry in perf.data file

Browse Source 
The value passed into the perf.data file for the CONFIGR register in ETMv4
was incorrectly being set to the command line options/ETMv3 value.

Adds bit definitions and function to remap this value to the correct ETMv4
CONFIGR bit values for all selected options.
