drm/i915/display: Drop check for doublescan mode in modevalid
[ Upstream commit 9d04eb20bc71a383b4d4e383b0b7fac8d38a2e34 ]
Since the DP/HDMI connector do not set connector->doublescan_allowed,
the doublescan modes will get automatically filtered during
drm_helper_probe_single_connector_modes().
Therefore check for double scan modes is not required and is dropped
from modevalid functions for both DP and HDMI.
