[PATCH v10 10/30] rcar-vin: fix handling of single field frames (top, bottom and alternate fields)

There was never proper support in the VIN driver to deliver ALTERNATING field format to user-space, remove this field option. The problem is that ALTERNATING filed order requires the sequence numbers of buffers returned to userspace to reflect if fields where dropped or not, something which is not

[PATCH v10 14/30] rcar-vin: add flag to switch to media controller mode

On Gen3 a media controller API needs to be used to allow userspace to configure the subdevices in the pipeline instead of directly controlling a single source subdevice, which is and will continue to be the mode of operation on Gen2. Prepare for these two modes of operation by adding a flag to
