[PATCH 13/46] kernel: Move prototype declaration to header file kernel/locking/lockdep_internals.h

Move prototype declaration of functions to header file
kernel/locking/lockdep_internals.h because they are used by more than
one file.

This eliminates the following warning in kernel/locking/lockdep.c:
kernel/locking/lockdep.c:2560:6: warning: no previous prototype for ‘trace_hardirqs_on_caller’ [-Wmissing-prototypes]
kernel/locking/lockdep.c:2613:6: warning: no previous prototype for ‘trace_hardirqs_off_caller’ [-Wmissing-prototypes]
