Replace the DRM_* logging macros used in gem helper files with the appropriate
ones specified in /include/drm/drm_print.h.

Changes in v3:
- Revert all changes to drm_gem_objects_lookup()
- Use drm_device as suggested in [1].
Changes in v2:
- Change drm_gem_objects_lookup() to take a drm_device* argument.
- Make appropriate changes to all calls of drm_gem_objects_lookup().
