Spares emits two symbol not declared warnings. The two functions in
question are declared already in a kernel header.

Add include directive to include kernel header.

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:

Thanks for fixing this!

Daniel
