Some platforms have dedicated IRQ lines for platform-specific System Errors
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.

Changes in v4 (Stefan):
- Remove 2nd check for PCI_EXP_TYPE_ROOT_PORT
- Change init_platform_service_irqs() from void to return int

Changes in v3 (Stefan):
- Restructure patches from 4 patches in v2 to now 2 patches in v3
- Rename of functions names
- init_platform_service_irqs() now uses "struct pci_dev *" instead of
  "struct pci_host_bridge *"
- pcie_init_platform_service_irqs() is called before pcie_init_service_irqs()
- Use more PCIe spec terminology as suggested by Bjorn (hopefully enough, I
  don't have the spec at hand)
