Well if you're fixing that by migrating to scpsys compatible, you might as well
resolve all of the warnings in one commit, removing that power-domain-cells
property in patch [2/4], otherwise this one is technically a fix for that.

Please squash [2/4] and [3/4], like that it just makes more sense.

Cheers,
Angelo
