Setting scan mode to "none" confuses some TVs like LG B8, which randomly change overscan procentage over time. Digital outputs like HDMI and DVI, handled by this controller, don't really need overscan, so we can always set scan mode to underscan. Actually, this is exactly what drm_hdmi_avi_infoframe_from_display_mode() already does, so we can just remove offending line.
