hw/isa/piix4: Decouple INTx-to-LNKx routing which is board-specific
pci_map_irq_fn's in general seem to be board-specific, and PIIX4's
pci_slot_get_pirq() in particular seems very Malta-specific. So move the
latter to malta.c to 1/ keep the board logic in one place and 2/ avoid
PIIX4 to make assumptions about its board.
