perf, x86: Call x86_setup_perfctr() from .hw_config()

Browse Source 
The perfctr setup calls are in the corresponding .hw_config()
functions now. This makes it possible to introduce config functions
for other pmu events that are not perfctr specific.

Also, all of a sudden the code looks much nicer.
