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
   4669     464       0    5133    140d panel-dsi-cm.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   4725     400       0    5125    1405 panel-dsi-cm.o
