powerpc/64s: Add lockdep for HPTE lock

Add lockdep annotation for the HPTE bit-spinlock. Modern systems don't
take the tlbie lock, so this shows up some of the same lockdep warnings
that were being reported by the ppc970. And they're not taken in exactly
the same places so this is nice to have in its own right.
