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 for DSS DPI output and HDMI Interrupt.

Add DT nodes for SIL9022 HDMI transmitter (TX), and the HDMI connector
on the phyBOARD-Lyra.

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.
