[RESEND PATCH v2 1/4] PCI: Add setup_platform_service_irq hook to struct pci_host_bridge

[Stefan Roese <sr@denx.de>]

From: Bharat Kumar Gogada <bharat.kumar.gogada@xilinx.com>

As per section 6.2.4.1.2, 6.2.6 in PCIe r4.0 error interrupts can
be delivered with platform specific interrupt lines.
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.
This hook is to register platform IRQ's to PCIe port services.
