It's not always clear what the best way is to handle unexpected
conditions: whether with ASSERT(), domain_crash(), BUG_ON(), or some

Add the XEN_IGD_PASSTHROUGH Kconfig option.

Use definitions from "hw/pci/pci_regs.h".
This also helps when using git-grep.

Make the PCII440FXState structure public, so it can be used out of

Xen relies on boot modules to perform early microcode updates. This commit adds
another mode, namely "builtin" via the BUILTIN_UCODE config parameter. If set,
the Xen image itself will contain the microcode updates. Upon boot, Xen
inspects its image for microcode blobs and performs the update.
