ACPI / power: 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
4622 304 8 4934 1346 drivers/acpi/power.o
File size After adding 'const':
text data bss dec hex filename
4846 80 8 4934 1346 drivers/acpi/power.o
