xen, gfx passthrough: add opregion mapping
...
The OpRegion shouldn't be mapped 1:1 because the address in the host
can't be used in the guest directly.
This patch traps read and write access to the opregion of the Intel
GPU config space (offset 0xfc).
The original patch is from Jean Guyader <jean.guyader@eu.citrix.com >

xen, gfx passthrough: retrieve VGA BIOS to work
...
Now we retrieve VGA bios like kvm stuff in qemu but we need to
fix Device Identification in case if its not matched with the
real IGD device since Seabios is always trying to compare this
ID to work out VGA BIOS.
