Subject: [PATCH] input: psmouse: constify attribute_group structures.

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
