[PATCH 15/20] sh: smp: Fix missing prototypes

arch/sh/kernel/smp.c:173:17: warning: no previous prototype for 'start_secondary' [-Wmissing-prototypes]
arch/sh/kernel/smp.c:324:5: warning: no previous prototype for 'setup_profiling_timer' [-Wmissing-prototypes]

Make start_secondary() static, as it is only used in this file.
Include <linux/profile.h> to fix the other warning.

There are no users outside this file, so make it static.
