We are transitioning to more organized bindings, so this must have
"-stat" suffix.

Merge these nodes either in one node with "-pins" or just under above
"-state".

Merge or -pins. This applies everywhere.

Wrong indentation. It should be aligned with previous gpio18 entry. This
applies everywhere.
