Add DSS, DSI and DPHY nodes to add base display support on AM62L[1].
AM62L shares a single video port for DPI and DSI output.

From: Devarsh Thakkar <devarsht@ti.com>
Add the SII9022 HDMI bridge and HDMI connector nodes, along with the
DPI pinmux configuration connecting VOUT0 to the bridge. Enable the DSS
and hook up its DPI output port to the SII9022 bridge input, and the
bridge output to the HDMI connector.
