Input: 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
  17755	   1312	     16	  19083	   4a8b	drivers/input/input.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  17947	   1120	     16	  19083	   4a8b	drivers/input/input.o
