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
