mtd: of_mtd_fixup(): fix given DT not the default one
We have to start searching for the mtd node starting in the given root node not
the defaukt (= barebox internal) one. This means the internal DT is always
fixed up. This leads to booting not fixed up DT when using external DTs.
This patch fixes the problem.
