Similarly to the core bus, this seems to have address ranges 0x03xxxxxx and
0x18xxxxxx on it, so put those into the ranges.

It probably also makes sense to name the bus according to what kind of
bus (axi, ahb, plb, ...) is used here. If the soc has nested buses
(e.g. an ahb connected to an axi bus,) then model both of them in the DT.
