Subject: [PATCH 42/58] kernel/events/hw_breakpoint.c: Add prototype for __weak stub of arch_unregister_hw_breakpoint

kernel/events/hw_breakpoint.c defines an empty stub of
arch_unregister_hw_breakpoint with __weak, for use on architectures
without an alternate implementation.  Define a prototype of that
function, to satisfy gcc (-Wmissing-prototypes) and Sparse (-Wdecl).

kernel/events/hw_breakpoint.c:247:28: warning: no previous prototype for ‘arch_unregister_hw_breakpoint’ [-Wmissing-prototypes]
