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
   2673	    368	      0	   3041	    be1	panel-tpo-td043mtea1.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   2737	    304	      0	   3041	    be1	panel-tpo-td043mtea1.o
