arch: add missing prepare_ftrace_return() prototypes
The prototype for prepare_ftrace_return() is architecture specific and
can't be in a global header. Since it's normally called from assembly,
it doesn't really need a prototype, but we get a warning if it's missing:
arch/csky/kernel/ftrace.c:147:6: error: no previous prototype for 'prepare_ftrace_return' [-Werror=missing-prototypes]
arch/microblaze/kernel/ftrace.c:22:6: error: no previous prototype for 'prepare_ftrace_return' [-Werror=missing-prototypes]
arch/mips/kernel/ftrace.c:305:6: error: no previous prototype for 'prepare_ftrace_return' [-Werror=missing-prototypes]
Add the prototypes for the three architectures that don't already have
one in asm/ftrace.h.
