I don't object to this patch.

However just FYI, it should not be necessary for correctness; The DT
matching order is supposed to be driven purely by the order of the
compatible values in the DT now, and not affected by the order of values
in the table. (This wasn't always the case, but was a bug that was fixed
IIRC by Thierry Reding).
