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.

Support for Intel IGD specific extensions to enable direct
assignment to virtual machines. This includes exposing an IGD
specific firmware table and read-only copies of the host bridge
and LPC bridge config space.
To enable Intel IGD assignment through vfio-pci, say Y.
