x86/pci: Set default irq domain in pcibios_add_device()
Now that interrupt remapping sets the irqdomain pointer when a PCI device is added it's possible to store the default irq domain in the device struct in pcibios_add_device(). If the bus to which a device is connected has an irq domain associated then this domain is used otherwise the default domain (PCI/MSI native or XEN PCI/MSI) is used. Using the bus domain ensures that special MSI bus domains like VMD work. This makes XEN and the non-remapped native case work solely based on the irq domain pointer in struct device for PCI/MSI and allows to remove the arch fallback and make most of the x86_msi ops private to XEN in the next steps.
