So far the policy we had on this is only to add to the DT the primary
purpose of these pins.

Even though that might seem arbitrary, it's the only way to prevent
anyone adding their own configuration for those pins, which would be a
mess to maintain and use. It's even more true since that sort of thing
is exactly where the overlays shine.

So, I'm ok with adding the uart4, but the uart2 should go.
