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
   6026	   2541	     12	   8579	   2183	drivers/edac/edac_mc_sysfs.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   6090	   2477	     12	   8579	   2183	drivers/edac/edac_mc_sysfs.o
