platform/x86: fujitsu-laptop: 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
   7474	   1205	     24	   8703	   21ff	drivers/platform/x86/fujitsu-laptop.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   7538	   1141	     24	   8703	   21ff	drivers/platform/x86/fujitsu-laptop.o
