cpu/hotplug: 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
12582 15361 20 27963 6d3b kernel/cpu.o
File size After adding 'const':
text data bss dec hex filename
12710 15265 20 27995 6d5b kernel/cpu.o
