PCI: Add nr_devfns parameter to pci_add_dma_alias()
[ Upstream commit 09298542cd891b43778db1f65aa3613aa5a562eb ]
Add a "nr_devfns" parameter to pci_add_dma_alias() so it can be used to
create DMA aliases for a range of devfns.
[bhelgaas: incorporate nr_devfns fix from James, update
quirk_pex_vca_alias() and setup_aliases()]
