arm64: dts: ti: k3-am62-verdin: Add Mezzanine with Toradex Display 10.1" LVDS

Browse Source 
Add a device tree overlay enabling the Toradex Capacitive Touch Display
10.1" LVDS on the Verdin Development Board with Verdin AM62 Mezzanine
expansion board. The panel connects via the AM62 OLDI0 on the Mezzanine
LVDS interface (J10). The panel is a LogicTechno LT170410-2WHC 10.1" WXGA
IPS LCD and the touch input is provided by an Atmel MaxTouch capacitive
touch controller.
