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
   5693     464       0    6157    180d drivers/input/keyboard/gpio_keys.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   5749     400       0    6149    1805 drivers/input/keyboard/gpio_keys.o
