uda1380 driver doesn't work without CONFIG_I2C anyway. Let's depend on it.

Note that this doesn't help when it's reverse-selected by others.
The same is true for an item with a prompt, but the item like this without prompt is supposed to be reverse-selected only, so adding "depends on" there is merely a placeholder.
That being said, currently the only way to guarantee the dependency by a reverse-selection is to put the depends-on to the selecting item, not to the selected item.
It's a generic problem of the kbuild implementation, and people know of it over a decade. It was discussed in the previous Plumbers conference, and developers agreed to improve the situation, so it may be a bit better in near future.
