arm64: dts: ti: k3-am69-aquila: Add 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. Used on Development Board
(J44), where DSI_1 is exposed via a Samtec LSS-130 connector.

The adapter 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.
