PCI: apple: Add INTx and per-port interrupt support
Add support for the per-port interrupt controller that deals with both INTx signalling and management interrupts. This allows the Link-up/Link-down interrupts to be wired, allowing the bring-up to be synchronised (and provide debug information). The framework can further be used to handle the rest of the per port events if and when necessary. Likewise, INTx signalling is implemented so that end-points can actually be used.
