'struct configfs_item_operations' and 'configfs_group_operations' are not
modified in this driver.

Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  34095	  15704	    128	  49927	   c307	drivers/gpu/drm/xe/xe_configfs.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  34447	  15352	    128	  49927	   c307	drivers/gpu/drm/xe/xe_configfs.o
