DDI A and E have 4 lanes to share, so if DDI A is using 4 lanes, there's nothing left for DDI E, which means there's no CRT port on the machine. The bit we're checking here is programmed at system boot and it cannot be changed afterwards, so we cannot change the amount of lanes reserved for each DDI port.
