Implement a pci host bridge specific to passthrough. Actually
this just inherits the standard one.

We will try to reuse assign_dev_load_option_rom in xen side, and
especially its a good beginning to unify pci assign codes both on
kvm and xen in the future.

bably don't matter to the
Gfx driver, but obviously any difference in display port connections
will so it should be fine with any PCH in case of passthrough.
So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
scenarios, 0x9cc3 for BDW(Broadwell).

basic gfx passthrough support:
- add a vga type for gfx passthrough
- register/unregister legacy VGA I/O ports and MMIOs for passthrough GFX

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.

Some registers of Intel IGD are mapped in host bridge, so it needs to
passthrough these registers of physical host bridge to guest because
emulated host bridge in guest doesn't have these mappings.

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

When we're working to support IGD GFX passthrough with qemu
upstream, instead of "-gfx_passthru" we'd like to make that
a machine option, "-machine xxx,gfx_passthru=on". This need
to bring several changes on tool side.

Currently IGD drivers always need to access PCH by 1f.0, and
PCH vendor/device id is used to identify the card.

And note actually that option "-gfx_passthru" is just introduced to
work for qemu-xen-traditional so we should get this away from
libxl__build_device_model_args_new() in the case of qemu upstream.
