media: dt-bindings: ovti,ov5640: Allow props from video-interface-devices

There is no reason to restrict the allowed rotation degrees to 0 and 180,
as the sensor can be mounted with any rotation.

Also, as all the properties described by video-interface-devices.yaml are
allowed for the image sensor, make them accepted by changing
"additionalProperties: false" to "unevaluatedProperties: false" at the
schema top-level.
