[Intel-gfx] [PATCH 9/9] drm/i915: Change SDVO fixed mode handling

[Ville Syrjala]

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

SDVO is the only connector type currently returning the VBT
fixed mode directly from .get_modes(), everyone else just
adds it to the fixed_modes list and then returns that from
.get_modes(). Adjust SDVO to follow the common behaviour.
