prep: qdev'ify Raven host bridge (SysBus)
Drop pci_prep_init() in favor of extended device state. Inspired by patches from Hervé and Alex. Assign the 4 IRQs from the board after device instantiation. This moves the knowledge out of prep_pci and allows for future machines with different IRQ wiring (IBM 40P). Suggested by Alex.
