hw: set interrupts using pci irq wrappers
pci_set_irq and the other pci irq wrappers use PCI_INTERRUPT_PIN config register to compute device INTx pin to assert/deassert. An irq is allocated using pci_allocate_irq wrapper only if is needed by non pci devices. Removed irq related fields from state if not used anymore.
