[0/4] Add support to register platform service IRQ

Message

Some platforms have dedicated IRQ lines for PCIe services like
AER/PME etc. The root complex on these platform will use these seperate
IRQ lines to report AER/PME etc., interrupts and will not generate
MSI/MSI-X/INTx interrupts for these services.
These patches will add new method for these kind of platforms
to register the platform IRQ number with respective PCIe services.

Bharat Kumar Gogada (4):
  PCI: Add setup_platform_service_irq hook to struct pci_host_bridge
  PCI: Add pci_check_platform_service_irqs
  PCI/portdrv: Check platform supported service IRQ's
  PCI: xilinx-nwl: Add method to setup_platform_service_irq hook

I'm taking a breather during the merge window.  As soon as -rc1 comes
out (probably Sunday), I'll start processing the patches in the queue.
