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
   8710    5452      23   14185    3769 drivers/platform/x86/samsung-laptop.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   8774    5388      23   14185    3769 drivers/platform/x86/samsung-laptop.o
