Subject: [PATCH 1/3] dt-bindings: display: bridge: add sam9x7-lvds compatible

Add the 'sam9x7-lvds' compatible binding, which describes the
Low Voltage Differential Signaling (LVDS) Controller found on Microchip's
sam9x7 series System-on-Chip (SoC) devices. This binding will be used to
define the properties and configuration for the LVDS Controller in DT.
