vfio/pci: Make IGD support a configurable option
Allow the code which provides extensions to support direct assignment
of Intel IGD (GVT-d) to be compiled out of the kernel if desired. The
config option for this was previously automatically enabled on X86,
therefore the default remains Y. This simply provides the option to
disable it even for X86.
