arm64: dts: ti: k3-am62-verdin: Add Toradex DSI to LVDS adapter with 10.1" display

Browse Source 
Add a device tree overlay for the Toradex DSI to LVDS Adapter with the
Toradex Capacitive Touch Display 10.1" LVDS. The adapter connects to the
Verdin DSI_1 interface. It is based on the Texas Instruments SN65DSI84
DSI-to-LVDS bridge and drives a LogicTechno LT170410-2WHC 10.1" WXGA LVDS
panel. Touch input is provided by an Atmel MaxTouch capacitive touch
controller.
