arm64: dts: ti: k3-am62-verdin: Add DSI to HDMI adapter overlay

Browse Source 
Add a device-tree overlay for the Toradex DSI to HDMI Adapter, an
accessory that connects to the Verdin DSI_1 interface and provides a
full-size HDMI Type-A output. The adapter is based on the Lontium
LT8912B DSI-to-HDMI bridge.

The overlay is also combined with the Verdin AM62 carrier board device
trees to provide ready-to-use DTBs for the Dahlia and Development Board
carriers, in both WiFi and non-WiFi SoM variants.
