[PATCH] input: psmouse: 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
  12850     740      12   13602    3522 drivers/input/mouse/psmouse-base.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  12914     676      12   13602    3522 drivers/input/mouse/psmouse-base.o
