Switching to case B, which is the current best practice, requires that the HDMI connector is always described in the live device tree, and a previous commit ensured this is always the case by adding an overlay in case the device tree does not comply. So now we can simply switch to the new mode and support DRM_BRIDGE_ATTACH_NO_CONNECTOR.
