[PATCH v4 2/6] arm64: dts: ti: k3-am62-main: Add node for DSS

[Aradhya Bhatia]

Add Display SubSystem (DSS) DT node for the AM625 SoC.

The DSS supports one each of video pipeline (vid) and video-lite
pipeline (vidl1). It outputs OLDI signals on one video port (VP1) and
DPI signals on another (VP2). The video ports are connected to the
pipelines via 2 identical overlay managers (ovr1 and ovr2).
