The kernel bootup is much faster with normal mode. In this case, there is a chance that the cros-ec-typec module get the actual typec port counts but not accurate from ec before ec is able to setup it. It will block the HDMI mux function. Hence, return -EPROBE_DEFER to put the device onto the deferred probe list when the typec count mismatch between ec and node.
