[PATCH 1/3][SRU][L/K/J] drm/i915/display: Drop check for doublescan mode in modevalid

[Koba Ko]

From: Ankit Nautiyal <ankit.k.nautiyal at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1993561 

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.
