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
8480 2024 4 10508 290c drivers/pci/pci-sysfs.o
File size After adding 'const':
text data bss dec hex filename
8736 1768 4 10508 290c drivers/pci/pci-sysfs.o
