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

File size After adding 'const':
   text    data     bss     dec     hex filename
   2721     304       0    3025     bd1 panel-tpo-td043mtea1.o
