arm64: dts: freescale: imx8mm-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 iMX8M Mini carrier board
device trees to provide ready-to-use DTBs for the Dahlia, Yavia and
Development Board carriers, in both WiFi and non-WiFi SoM variants.
