[PATCH v10 9/9] drm: Remove superfluous print statements in DRM core

[Siddh Raman Pant]

There are a couple of superfluous print statements using the drm_*
macros, which do stuff like printing newlines, print OOM messages
(OOM while allocating memory is already supposed to be noisy), and
printing strings like "Initialised" with no extra info whatsoever.

Thus, remove a couple of these superfluous strings.
