dt-bindings: display: tegra: Support SOR crossbar configuration
The SOR has a crossbar that can map each lane of the SOR to each of the
SOR pads. The mapping is usually the same across designs for a specific
SoC generation, but every now and then there's a design that doesn't.
Allow the crossbar configuration to be specified in device tree to make
it possible to support these designs.
