Conversion of the printk based drm logging macros to the struct
drm_device based logging macros in display/intel_dp_aux_backlight.c.
This also involves extracting the drm_i915_private device pointer from
various intel types to use in the macros.
Note that this converts DRM_DEBUG_DRIVER to drm_dbg().

I'm holding on with this one for a bit, as I'd probably like to get
other changes merged to this file first. Sorry.
