PCI: PCIe portdrv: Aviod using service devices with wrong interrupts
The PCI Express port driver should not attempt to register service devices that require the ability to generate interrupts if generating interrupts is not possible. Namely, if the port has no interrupt pin configured and we cannot set up MSI or MSI-X for it, there is no way it can generate interrupts and in such a case the port services that rely on interrupts (PME, PCIe HP, AER) should not be enabled for it.
