[Intel-gfx] [PATCH 08/17] drm/i915: Store the HDMI default entry in the bug trans struct

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Store the default HDMI buf trans entry in struct intel_ddi_buf_trans
so that it's next to the actual table. This let's us start ridding
ourselves of some platofrm specifics in intel_ddi_hdmi_num_entries().
