But those are not being added to i915_debugfs.c, only to 
intel_guc_submission.c. So why is the include being added here?

this is not "guc log" function, it is "guc ct" one, so:

  void intel_guc_ct_print_info(struct intel_guc_ct *ct,

nit: maybe

  drm_puts(p, "CT %s\n", enableddisabled(false));

don't you want to print size ?
or GGTT offset ?

hmm, what about adding helper:

  static void dump_ctb(struct intel_guc_ct_buffer *ctb, *p)
  {
	drm_printf(p, "Size: %u\n", ctb->size);
	drm_printf(p, "Space: %u\n", atomic_read(&ctb->space) * 4);
	drm_printf(p, "Head: %u\n", ctb->desc->head);
	drm_printf(p, "Tail: %u\n", ctb->desc->tail);
  }

and then:

	drm_printf(p, "H2G:\n");
	dump_ctb(&ct->ctbs.send, p);
	drm_printf(p, "G2H:\n");
	dump_ctb(&ct->ctbs.recv, p);

or

	dump_ctb(&ct->ctbs.send, "H2G", p);
	dump_ctb(&ct->ctbs.recv, "G2H", p);
