platform/x86: compal-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.

   text	   data	    bss	    dec	    hex	filename

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   6845	   6080	     34	  12959	   329f	drivers/platform/x86/compal-laptop.o
