powerpc: Add missing prototypes for hw_breakpoint_handler() & arch_unregister_hw_breakpoint() 

In commit 5aae8a5370 ("powerpc, hw_breakpoints: Implement
hw_breakpoints for 64-bit server processors") function
hw_breakpoint_handler() and arch_unregister_hw_breakpoint() were added
without function prototypes in hw_breakpoint.h header.

Fix the following warning(s) (treated as error in W=1):
  arch/powerpc/kernel/hw_breakpoint.c:106:6: error: no previous prototype for ‘arch_unregister_hw_breakpoint’
  arch/powerpc/kernel/hw_breakpoint.c:209:5: error: no previous prototype for ‘hw_breakpoint_handler’
