arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 7" DSI

Browse Source 
Add a device tree overlay for the Toradex Capacitive Touch Display 7"
DSI on the Verdin DSI_1 interface. The display features an internal
Texas Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi
RVT70HSLNWCA0 7" WSVGA IPS TFT LCD panel. The touch input is provided
by an Ilitek ILI2132 capacitive touch controller.
