arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS V2

Browse Source 
Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS V2 connected via Verdin AM62 OLDI on carrier boards exposing LVDS
interface (e.g., Mallow). The panel is an Opto Logic SCX1001511GGC49 10.1"
WXGA TFT LCD and the touch input is provided by an ILITEK ILI251x
capacitive touch controller.
