perf_counter: Make set_perf_counter_pending() declaration common

Browse Source 
At present, every architecture that supports perf_counters has to
declare set_perf_counter_pending() in its arch-specific headers.
This consolidates the declarations into a single declaration in one
common place, include/linux/perf_counter.h.  On powerpc, we continue
to provide a static inline definition of set_perf_counter_pending()
in the powerpc hw_irq.h.

Also, this removes from the x86 perf_counter.h the unused null
definitions of {test,clear}_perf_counter_pending.
