[PATCH v3 6/8] dt-bindings: rcar-vin: Add 'hsync-as-de' custom prop

Document the boolean custom property 'renesas,hsync-as-de' that indicates
that the HSYNC signal is internally used as data-enable, when the
CLKENB signal is not connected.

As this is a VIN specificity create a custom property specific to the R-Car
VIN driver.
