PCI: Constify label 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
930 320 0 1250 4e2 drivers/pci/pci-label.o
File size After adding 'const':
text data bss dec hex filename
1058 192 0 1250 4ca drivers/pci/pci-label.o
