[Intel-gfx] [PATCH 3/7] drm/i915/rc6: convert to struct drm_device based logging macros.

[Wambui Karuga]

Converts various instances of the printk based drm logging macros to use
the struct drm_device logging macros. This also involves extracting the
drm_i915_private device from intel types in some cases.

Note that this converts DRM_DEBUG_DRIVER() to drm_dbg().
