PM: hibernate: 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 After adding 'const':

   6396	    424	    308	   7128	   1bd8	kernel/power/hibernate.o
