[PATCH 12/12] drm/i915/panel: automatic conversion to drm_device based logging macros.

Converts various instances of the printk based drm logging macros to the struct drm_device based logging macros in i915/display/intel_panel.c using the following coccinelle script that transforms based on the existence of a struct drm_i915_private device pointer: @@ identifier fn, T; @@

Checkpatch warnings were addressed manually.
