[Intel-gfx] [PATCH v2 05/11] drm/i915: Wrap g4x+ DP/HDMI audio enable/disable

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Put a wrapper around the intel_audio_codec_{enable,disable}()
calls in the g4x+ DP/HDMI code. We shall move the presence
detect enable/disable into the wrappers later.
