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. Signed-off-by: Thierry Reding <treding@nvidia.com>
