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 V2 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 an Opto Logic SCX1001511GGC49 10.1" WXGA
TFT LCD LVDS and the touch input is provided by an ILITEK ILI251x
capacitive touch controller.
