drm/doc: Overview documentation for drm_mm.c
kerneldoc polish will follow in the next patch. Hopefully documenting the lru scan support a bit better spurs someone to give this a shot in the ttm eviction code. At least in i915 it helped quite a lot with memory thrashing on platforms where eviction was (we've fixed that too meanwhile) fairly expensive.
