media: i2c: Remove common dependencies from sensor drivers

As selecting V4L2_FWNODE, MEDIA_CONTROLLER and VIDEO_V4L2_SUBDEV_API are
now selected by the top level menu, they can be dropped from the
individual drivers. Also dropped selecting V4L2_ASYNC for a single driver
as this is already implied by V4L2_FWNODE.

Similarly, the I2C dependency is now also in the top level menu, so remove
it, as well as VIDEO_DEV which isn't needed by camera sensor drivers.
