Set DW HDMI platform data's output_port to 1 in imx8mp_dw_hdmi_probe() so that dw_hdmi_probe() called by imx8mp_dw_hdmi_probe() can tell the DW HDMI bridge core driver about the output port we are using, hence the next bridge can be found in dw_hdmi_parse_dt() according to the port index, and furthermore the next bridge can be attached to bridge chain in dw_hdmi_bridge_attach() when the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is set. The output_port value aligns to the value used by devicetree. This is a preparation for making the i.MX8MP LCDIF driver use drm_bridge_connector which requires the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag.
