dt-bindings: panel: lvds: Document power-supply property 



The power-supply property is used by a vast majority of panels, including
panel-simple. Let's document it as a common property

Power

-----



- power-supply: display panels require power to be supplied. While several

  panels need more than one power supply with panel-specific constraints

  governing the order and timings of the power supplies, in many cases a single

  power supply is sufficient, either because the panel has a single power rail,

  or because all its power rails can be driven by the same supply. In that case

  the power-supply property specifies the supply powering the panel as a phandle

  to a regulator.
