[PATCH 5/5] perf: Declare hw_perf_{dis,en}able() in perf_event.h

[Namhyung Kim <namhyung@gmail.com>]

Since they can be defined in arch-specific code declare them in
perf_event.h and remove following warnings from sparse:

 kernel/perf_event.c:83:13: warning: symbol 'hw_perf_disable' was not declared. Should it be static?
 kernel/perf_event.c:84:13: warning: symbol 'hw_perf_enable' was not declared. Should it be static?
