Subject: [PATCH 2/8] dt-bindings: display: bridge: thc63lvd1024: Add lvds map property

The THC63LVD1024 LVDS to RGB bridge supports two different input mapping
modes, selectable by means of an external pin.

Describe the LVDS mode map through a newly defined mandatory property in
device tree bindings.
