drm/i915/ring_submission: use drm_device based logging macros.

Replace the use of printk based drm logging macros to the struct
drm_device based logging macros in i915/gt/intel_ring_submission.c.
This was done using the following semantic patch that transforms based
on the existence of a drm_i915_private device:
@@
identifier fn, T;
@@

fn(...) {
...
struct drm_i915_private *T = ...;
<+...
(
-DRM_INFO(
+drm_info(&T->drm,

+drm_err(&T->drm,

+drm_dbg_kms(&T->drm,

-DRM_DEBUG_DRIVER(
+drm_dbg(&T->drm,

-DRM_DEBUG_ATOMIC(
+drm_dbg_atomic(&T->drm,
...)

}

}

New checkpatch warnings were fixed manually.

Note that this converts DRM_DEBUG_DRIVER to drm_dbg().
