[PATCH] powerpc: Merge asm-ppc*/rwsem.h

Merge asm-ppc*/rwsem.h into include/asm-powerpc.
Removed smp_*mb() memory barriers from the ppc32 code
as they are now burried in the atomic_*() functions as
suggested by Paul, implemented by Arnd, and pushed out
by Becky.  I am not the droid you are looking for.

This patch depends on Becky's atomic.h merge patch.
