[PATCH] powerpc: Merge (move) numnodes.h and sparsemem.h

The ppc64 versions of numnodes.h and sparsemem.h can be safely moved
to asm-powerpc with no changes apart from changing the #define to the
standard _ASM_POWERPC_ form.  There are no ppc32 versions of these
files, because they only have any effect if CONFIG_SPARSEMEM is
enabled, which it never can be on ppc32.

Built and booted on pSeries (POWER5), built for 32-bit powermac.
