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
