[Intel-gfx] [PATCH 05/11] drm/i915: Combine the EDID fixed_mode+downclock_mode lookup into one

[Ville Syrjala]

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

The intel_panel_add_edid_fixed_mode() vs.
intel_panel_add_edid_downclock_mode() split is not really
helpful. Let's just roll those into a single function so
that the connector init code doesn't have to care too much
about this. All we need to know is whether DRRS should be
allowed or not.
