[PATCH v2 42/55] dt-bindings: media: rkisp1: Add port for parallel interface

[Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>]

From: Paul Elder <paul.elder@xxxxxxxxxxxxxxxx>

The rkisp1 can take an input on the parallel interface. Add a port for
it, and update the required field. At least one port is required, and
both may be specified.
