Daniel Bristot de Oliveira f7d9f6370e trace/osnoise: Fix 'no previous prototype' warnings 
kernel test robot reported some osnoise functions with "no previous
prototype."

Fix these warnings by making local functions static, and by adding:

 void osnoise_trace_irq_entry(int id);
 void osnoise_trace_irq_exit(int id, const char *desc);

to include/linux/trace.h.

Fixes: bce29ac9ce ("trace: Add osnoise tracer")
