Link training will sometimes fail if the DP link is enabled when tc_main_link_enable() is called. The driver makes sure the DP link is disabled when the DP output is disabled, and we never enable the DP without first disabling it, so this should never happen. However, as the HW behavior seems to be somewhat random if DP link has erroneously been left enabled, let's add a WARN_ON() for the case and set DP0CTL to 0.
