[PATCH] drm/xe/configfs: Constify struct configfs_item_operations and configfs_group_operations

[Christophe JAILLET]

'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
