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
   5287     448       0    5735    1667 drivers/input/rmi4/rmi_f34.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   5339     384       0    5723    165b drivers/input/rmi4/rmi_f34.o
