pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). Add domain parameter to CDV_MSG_READ32, CDV_MSG_WRITE32, MRST_MSG_READ32, MRST_MSG_WRITE32, MDFLD_MSG_READ32, MDFLD_MSG_WRITE32. Extract pci_dev from struct drm_device and use pdev to find the domain number while calling pci_get_domain_bus_and_slot().
