platform/x86: samsung-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
   8710	   5452	     23	  14185	   3769	drivers/platform/x86/samsung-laptop.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   8774	   5388	     23	  14185	   3769	drivers/platform/x86/samsung-laptop.o
