arm64: dts: ti: k3-am69-aquila: Add Toradex Capacitive Touch Display 7" DSI with adapter

Browse Source 
Add a device tree overlay for the Toradex Capacitive Touch Display 7" DSI
used with the Toradex DSI Display Adapter on the Aquila Development Board.
On this board, DSI_1 is exposed on connector J44 through a Samtec LSS-130
connector, and the adapter converts it to an FFC/FPC connector.

The display includes an internal Texas Instruments SN65DSI83 DSI-to-LVDS
bridge driving a Riverdi RVT70HSLNWCA0 7" WSVGA IPS TFT LCD panel. Touch
input is provided by an Ilitek ILI2132 capacitive touch controller.
