[Intel-gfx] [PATCH v3 08/13] drm/i915/sdvo: Only use "presence detect" for has_audio readout

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

Align the SDVO audio code with the native HDMI/DP audio and
use just the "presence detect" bit for the has_audio readout.
The "ELD valid" bit will be used for ELD readout soon.
