    v1->v2: Style and formatting changes suggested by Rob Herring.
    License remains GPL-2.0 as the other powerpc dtses are the same, happy
    to change if there is a different preferred default.
    v2->v3: Re-added address-cells accidentally removed in v2.
    Marked latte as a simple-bus, since it is.
    v3->v4: Updated to match devicetree bindings. Model also changed to
    wup-101 in preparation for potentially different devices in future
    (cat-dev etc.) Chosen node removed.
