[PATCH 1/7] drm/i915: Remove DRM_MODE_FLAG_DBLSCAN checks from .mode_valid() hooks

[Ville Syrjala]

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

We never set connector->doublescan_allowed, so the probe helper
already filters out all doublescan modes for us.

Sadly we still need to keep the explicit doublescan checks
in .compute_config as outlined in commit e4dd27aadd20
("drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSI")
