Subject: [PATCH 1/2] hw_breakpoint: Remove unused '__register_perf_hw_breakpoint' declaration

commit b326e9560a28 ("hw-breakpoints: Use overflow handler instead of
the event callback") removed '__register_perf_hw_breakpoint' function
usage and replaced it with 'register_perf_hw_breakpoint' function.

Remove the left-over unused '__register_perf_hw_breakpoint' declaration
from 'hw_breakpoint.h' as well.
