The number of pages is a dimm property. Move it to the dimm struct. After this change, it is possible to add sysfs nodes for the DIMM's that will properly represent the DIMM stick properties, including its size. A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when the memory controller represents the memory via chip select rows.
