These gpio names are due to old DT bindings not following the
"-gpio"/"-gpios" conventions. Handle it using a quirk so the
driver can just look up the GPIOs.

I suppose this is a run-time dependency only for the other patches?
Can I just pick it up into my tree?

You can, I was just thinking about bisectability and the low risk of collisions
with other patches. (Actually no-one gets hurt if it's applied to both trees
either, which IMO is perfectly fine in cases like this.)

Nah, Stephen Rothwell will auto-yell at you for that. I'm fine either way.

If we get any conflicts in next, then we'll deal with it with immutable tags.
