[PATCH] powerpc: fix sparse warning, include kernel header

[Daniel Axtens]

Hi Tobin,

I have built the kernel with the ppc6xx_defconfig with and without your
patch.

Using my smart-sparse-diff tool[1], I have confirmed the warning
disappears:

-/scratch/dja/linux/arch/powerpc/kernel/swsusp.c:17:6: warning: symbol 'save_processor_state' was not declared. Should it be static?
-/scratch/dja/linux/arch/powerpc/kernel/swsusp.c:31:6: warning: symbol 'restore_processor_state' was not declared. Should it be static?

As such, this patch is:

Reviewed-by: Daniel Axtens <dja at axtens.net>

Thanks for fixing this!

Regards,
Daniel
