Particular laptops comes with two USB Type-C ports, both supporting DP alt mode. Enable output on both of them. Explicitly list supported frequencies including HBR3/8.1Gbps for all external DisplayPort(s). Due to support missing in the USB/DisplayPort combo PHY driver, the external DisplayPort is limited to 2 lanes.
