Set up the high-definition multimedia interface (HDMI) display

The display subsystem provides the Weston and Wayland compositors, along with libdrm APIs, all of which interact with the DPU driver to render the Wayland client applications. Use the sample test applications to evaluate the basic rendering of Wayland applications and to connect to the HDMI display.
