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

File size After adding 'const':
text data bss dec hex filename
9496 944 0 10440 28c8 drivers/input/touchscreen/elants_i2c.o
