This is not inserted in the list alphabetically. It's not very well
sorted today either, but it should probably go above exynos.

Also, there are a number of configs that _select_ DEBUG_AT91_UART in
the list above, but they don't depend on AT91. So what can happen is
that you can select those, and then they will enable this option
(which will spit out a warning about unfulfilled dependency).

You should probably make the choices that select this option also
depend on AT91?
