rust: pci: add irq accessors
These accessors can be used to retrieve a irq::Registration or a
irq::ThreadedRegistration from a pci device. Alternatively, drivers can
retrieve an IrqRequest from a bound PCI device for later use.
These accessors ensure that only valid IRQ lines can ever be registered.
