[PATCH 4/6] arm64: dts: freescale: imx8mp-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS V2

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa at toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS V2 connected via Verdin iMX8M Plus LCDIF 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.
