[PATCH] input: elants_i2c: constify attribute_group structures.

[Arvind Yadav]

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
   9448    1008       0   10456    28d8 drivers/input/touchscreen/elants_i2c.o

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