[PATCH] input: ads7846: 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
   9086     624       0    9710    25ee drivers/input/touchscreen/ads7846.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   9198     496       0    9694    25de drivers/input/touchscreen/ads7846.o
