edac: Don't initialize csrow's first_page & friends when not needed
Almost all edac drivers initialize csrow_info->first_page, csrow_info->last_page and csrow_info->page_mask. Those vars are used inside the EDAC core, in order to calculate the csrow affected by an error, by using the routine edac_mc_find_csrow_by_page(). However, very few drivers actually use it: e752x_edac.c e7xxx_edac.c i3000_edac.c i82443bxgx_edac.c i82860_edac.c i82875p_edac.c i82975x_edac.c r82600_edac.c There also a few other drivers that have their own calculus formula internally using those vars. All the others are just wasting time by initializing those data. While initializing data without using them won't cause any troubles, as those information is stored at the wrong place (at csrows structure), it is better to remove what is unused, in order to simplify the next patch.
