First pass of conversion to the new struct drm_based device logging
macros in the drm/i915/gem directory. This conversion was achieved using
the following coccinelle script that transforms based on the existence
of a straightforward struct drm_i915_private device:

This changes DRM_UT_CORE to DRM_UT_DRIVER so our typical drm.debug=0xe becomes much more spammy.
