[PATCH-for-5.0 v2 6/6] hw/pci-host: Add Kconfig entry to select the IGD Passthrough Host Bridge

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Add the INTEL_IGD_PASSTHROUGH Kconfig option.

Since it is implied by the PCI_I440FX option, this does not change
the default selection. However users are now able to deselelect it.
