pci defines PCI_DEVFN(), PCI_SLOT(), and PCI_FUNC() interfaces, however, it doesn't have interfaces to return PCI bus and PCI device id. Drivers (AMD IOMMU, and AER) have module specific definitions for PCI_BUS() and AMD_IOMMU driver also has a module specific interface to calculate PCI device id from bus number and devfn.
This patch set adds PCI_BUS(), and PCI_DEVID() to pci.h, changes are to use PCI_BUS() from pci. Changes AMD_IOMMU driver to use PCI_BUS() and PCI_DEVID() from pci.
