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.
