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
   3152    1096       8    4256    10a0 processor_thermal_device.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   3216    1032       8    4256    10a0 processor_thermal_device.o
