mm: fix sparsemem configuration
Russell King [Mon, 26 Oct 2009 23:50:12 +0000 (16:50 -0700)]
Currently, sparsemem is only available if EXPERIMENTAL is enabled.
However, it hasn't ever been marked experimental.

It's been about four years since sparsemem was merged, and we have
platforms which depend on it; allow architectures to decide whether
sparsemem should be the default memory model.
