media: i2c: refer to config VIDEO_DEV to make ov08x40 image sensor driver usable

Commit 9958d30f ("media: Kconfig: cleanup VIDEO_DEV dependencies")
removes the config VIDEO_V4L2 as it is merged with config VIDEO_DEV.

Long after this change, commit 38fc5136 ("media: i2c: Add ov08x40 image
sensor driver") introduces and refers to the removed config VIDEO_V4L2,
basically making this driver impossible to build, test and use due to
dependencies that cannot be met.

Refer to config VIDEO_DEV instead to make this driver usable.
