drm/bridge: tc358767: move video stream setup to tc_main_link_stream
The driver currently sets the video stream registers in tc_main_link_setup. One should be able to establish the DP link without any video stream, so a more logical place is to configure the stream in the tc_main_link_stream. So move them there.
