[PATCH v1 1/2] dt-bindings: display: panel: Add LG LP156WF1

[Vitor Soares <ivitro@gmail.com>]

From: Vitor Soares <vitor.soares@toradex.com>

Add device tree binding for the LG LP156WF1 15.6" Full-HD (1920x1080)
dual-channel LVDS panel.

Also add lg,lp156wf1 to the panel-lvds.yaml exclusion list to prevent
false schema matches.

+  The LP156WF1 from LG is a 15.6" Full-HD dual-LVDS panel.
+  A dual-LVDS interface is a dual-link connection with even pixels traveling
+  on one link, and with odd pixels traveling on the other link.
