Subject: PM / sleep: 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
   3802	    624	     32	   4458	   116a	kernel/power/main.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   3866	    560	     32	   4458	   116a	kernel/power/main.o
