attribute_group are not supposed to change at runtime. All functions
working with attribute_group 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
   5227	    560	      0	   5787	   169b	panel-sony-acx565akm

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   5291	    496	      0	   5787	   169b	panel-sony-acx565akm.o
