[PATCH v10 08/10] drm/mediatek: mtk_hdmi_common: Add var to enable interlaced modes

[Louis-Alexis Eyraud]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno at collabora.com>

Add an interlace_allowed bool member to struct mtk_hdmi_ver_conf
which will be used to signal whether interlaced modes are supported
by the bridge (in our case, the HDMI IP), and enable it for HDMIv2.
