drm/xe/configfs: Fix documentation warning

Fix this warning while building the documentation:

	Documentation/gpu/xe/xe_configfs:9: drivers/gpu/drm/xe/xe_configfs.c:138:
	WARNING: Definition list ends without a blank line; unexpected unindent.

That also makes it better formatted in the output.

While at it, also fix the underline length in "Overview".
