Subject: [PATCH] edac: i7core: constify attribute_group structures.

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  12589	   1216	      8	  13813	   35f5	drivers/edac/i7core_edac.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  12717	   1088	      8	  13813	   35f5	drivers/edac/i7core_edac.o
