Subject: [PATCH v2 2/6] drm_dbg: add trailing newlines to msgs

By at least strong convention, a print-buffer's trailing newline says
"message complete, send it".  The exception (no TNL, followed by a call
to pr_cont) proves the general rule.

Most DRM.debug calls already comport with this: 207 DRM_DEV_DEBUG,
1288 drm_dbg.  Clean up the remainders, in maintainer sized chunks.

No functional changes.
