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
4028 1088 0 5116 13fc drivers/gpu/drm/i915/i915_sysfs.o
File size After adding 'const':
text data bss dec hex filename
4196 928 0 5124 1404 drivers/gpu/drm/i915/i915_sysfs.o
