[PARISC] Make superio.c initialize before any driver needs it
Convert superio_init to use PCI_FIXUP_FINAL as ohci_pci being called before superio_probe really makes a mess. superio_init will then fail to register irq 20 (the "SuperIO" irq) and BUG() because ohci_pci has stolen it before superio_fixup_irq can be moved USB to irq 1.
