This patchset:
1) adds support for MSI interrupt vectors to be used for Roor Port services
2) adds support for DPC Root Port service interrupt

The patchset has been tested on Hisilicon Hip08 Chipset

Changes from v1:
According to comments from Christoph Hellwig in
https://www.spinics.net/lists/kernel/msg2508842.html
and
https://www.spinics.net/lists/kernel/msg2508850.html

- reduced the calls of pci_alloc_irq_vectors by ORing PCI_IRQ_MSIX and 
  PCI_IRQ_MSI
- used a unique macro for the max number of MSI/MSIx interrupt vectors
- reworked pcie_init_service_irqs() to call pci_alloc_irq_vectors() only
  for legacy IRQ 

Gabriele Paoloni (1):
  PCI/portdrv: add support for different MSI interrupts for PCIe port
    services

gabriele paoloni (1):
  PCI/portdrv: allocate MSI/MSIx vector for DPC RP service
