attribute_group are not supposed to change at runtime. All functions
working with attribute_group 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
  15426    4952     187   20565    5055 drivers/video/fbdev/uvesafb.o

File size after adding 'const':
   text    data     bss     dec     hex filename
  15490    4888     187   20565    5055 drivers/video/fbdev/uvesafb.o
