bus: mvebu-mbus: allow several windows with the same target/attribute
Having multiple windows with the same target and attribute is actually legal, and can be useful for PCIe windows, when PCIe BARs have a size that isn't a power of two, and we therefore need to create several MBus windows to cover the PCIe BAR for a given PCIe interface.
