[PATCH v3 4/8] arm64: dts: ti: k3-am62x-sk-common: Add HDMI support

[Aradhya Bhatia <a-bhatia1@ti.com>]

Add DT nodes for sil9022 HDMI transmitter (TX), and the HDMI connector
on the AM625 SK and AM62-LP SK platforms.

Additionally, connect the outputu of DSS (VP2) with input of the HDMI TX,
and the output of HDMI TX to the input of the HDMI connector.
