perf cs-etm: Rethink kernel address initialisation

Browse source 
Moving initialisation of the kernel start address to function
cs_etm__setup_queues(), considered to be the common denominator for
queue initialisation.  That way we don't have to repeat the same code
at different places.

No change of functionatlity is introduced by this patch.
