[POWERPC] Kill sparse warnings in kprobes

Fix sparse warnings in powerpc kprobes:

  CHECK   arch/powerpc/kernel/kprobes.c
arch/powerpc/kernel/kprobes.c:277:6: warning: symbol 'kretprobe_trampoline_holder' was not declared. Should it be static?
arch/powerpc/kernel/kprobes.c:287:15: warning: symbol 'trampoline_probe_handler' was not declared. Should it be static?
arch/powerpc/kernel/kprobes.c:525:16: warning: symbol 'jprobe_return_end' was not declared. Should it be static?

Fix along the same lines as http://lkml.org/lkml/2008/2/13/642
