That was done so that we don't get devicetree validation issues on our branch;
eventually, there were no driver changes to support that binding change, and
it's there just to validate commit 2/2.

Of course the media maintainers do know about this so there will be no merge
conflict - but yes next time I'll let them pick these instead, it's probably
easier for everyone, besides simply being the proper thing to do.
