edac: move nr_pages to dimm struct

Browse Source 
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.
