The DSS outputs DPI signals via its second video port (VP2). The DPI output from DSS is 24 bits (RGB888) and is forwarded to an HDMI transmitter (SIL9022) on the board. Add pinmux info for DSS DPI output. Add DT nodes for SIL9022 HDMI transmitter (TX), and the HDMI connector on the AM62A7-SK platforms. Additionally, connect the output of DSS (VP2) with input of the HDMI TX, and the output of HDMI TX to the input of the HDMI connector.
