Subject: [PATCH] ps3: "mm/Kconfig" fix

sparsemem-make-sparsemem-vmemmap-selectable.patch introduces a little bug.

SPARSEMEM_VMEMMAP can be enabled in an architecture that doesn't support it. If the
architecture supports SPARSEMEM_VMEMMAP, SPARSEMEM_VMEMMAP_ENABLE is enabled,
so SPARSEMEM_VMEMMAP should depend on it.
