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.

   text    data     bss     dec     hex filename

File size After adding 'const':
   text    data     bss     dec     hex filename
   6703     240       0    6943    1b1f drivers/hwmon/hwmon.o
