Subject: [PATCH 1/4] PCI: Add setup_platform_service_irq hook to struct pci_host_bridge

Add setup_platform_service_irq hook to struct pci_host_bridge.
Some platforms have dedicated interrupt line from root complex to
interrupt controller for PCIe services like AER/PME etc.
This hook is to register platform IRQ's to PCIe port services.
