    LinuxKPI: pci: allocate entire pci_dev hiereachy up to root port on attach

    In linux_pci_attach_device() allocate a LinuxKPI pci_dev for each device in
    the hierarchy up to the root port[1] as we cannot do that later on demand
    as we may be in a context where we may not sleep.

    Take special care of DRM as there is a non-PCI device in the chain which
    needs to be skipped.

    iwlwifi(4) can hit this case called from a callout.

    While here leave a comment as the cleanup order of
    linux_pci_attach_device() needs correction seperately.
