Subject: Add necessary #includes to asm-powerpc/spu.h.

From: Maynard Johnson <maynardj@us.ibm.com>

This patch adds a couple of #includes to asm-powerpc/spu.h to
prevent compilation warnings that can occur when spu.h is
included from a source file where fs.h and notifier.h have
not been included already.

Thanks for pointing this out. I'm fixing this in a different way though,
with by adding forward-declarations of the structures to spu.h in order
to avoid making the include hierarchy worse. I'll submit that in a clean
patch along with my next batch of fixes.
