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
   5147	    560	      0	   5707	   164b	panel-sony-acx565akm.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   5211	    496	      0	   5707	   164b	panel-sony-acx565akm.o
