[media] media: rcar-vin: add support for V4L2_FIELD_ALTERNATE The HW can capture both ODD and EVEN fields in separate buffers so it's possible to support V4L2_FIELD_ALTERNATE. This patch add support for this mode. At probe time and when S_STD is called the driver will default to use V4L2_FIELD_INTERLACED if the subdevice reports V4L2_FIELD_ALTERNATE. The driver will only change the field type if the subdevice implements G_STD, if not it will keep the default at V4L2_FIELD_ALTERNATE. The user can always explicitly ask for V4L2_FIELD_ALTERNATE in S_FMT and the driver will use that field format.
