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 After adding 'const':
   text    data     bss     dec     hex filename
   1751     528       0    2279     8e7 int3400_thermal.o
