[PATCH 4/5] drm/bridge: imx8mp-hdmi-tx: Set output_port to 1

[Liu Ying]

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.
