powerpc/amigaone: Generic device tree for all AmigaOne boards
This device tree does not provide the correct CPU name, as various CPU models and revisions are used in AmigaOnes. Also the PCI root node does not contain a interrupt mapping property, as all boards have different interrupt routing. However the kernel can do a 1:1 mapping of all PCI interrupts, as only i8259 legacy interrupts are used.
