[PATCH 1/2] dt-bindings: media: video-interfaces: add support for dual edge sampling

[Michael Riesch <michael.riesch@wolfvision.net>]

Some devices support sampling of the parallel data at both edges of the
interface pixel clock in order to reduce the pixel clock by two.
Use the pclk-sample property to reflect this feature in the device tree.
