media: v4l: cadence: add VIDEO_V4L2 dependency
The cadence media drivers can be built-in while the v4l2 core is a loadable
module. This is a mistake and leads to link errors:
drivers/media/v4l2-core/v4l2-fwnode.o: In function `v4l2_async_register_subdev_sensor_common':
v4l2-fwnode.c:(.text+0x12f0): undefined reference to `v4l2_async_subdev_notifier_register'

cdns-csi2tx.c:(.text+0xa9c): undefined reference to `v4l2_async_register_subdev'
An explicit Kconfig dependency on VIDEO_V4L2 avoids the problem.
