[PATCH] PM: hibernate: constify attribute_group structures.

[Arvind Yadav]

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
   6332	    488	    308	   7128	   1bd8	kernel/power/hibernate.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   6396	    424	    308	   7128	   1bd8	kernel/power/hibernate.o
