I ran into some kind of fail with VT-d superpage on Geminlake igfx,
so without any better ideas let's just disable it.
Additionally Skylake/Broxton igfx have known issues with VT-d
superpage as well, so let's disable it there as well. This should
let us re-enable frame buffer compression (FBC) for some extra
power savings when the display is on.

While running "gem_exec_big --r single" from igt-gpu-tools on
Geminilake as soon as a 2M mapping is made I tend to get a DMAR
write fault. Strangely the faulting address is always a 4K page
and usually very far away from the 2M page that got mapped.
But if no 2M mappings get used I can't reproduce the fault.
I also tried to dump the PTE for the faulting address but it actually
looks correct to me (ie. definitely seems to have the write bit set):
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 7fa8a78000 [fault reason 05] PTE Write access is not set
DMAR: fault 7fa8a78000 (level=1) PTE = 149efc003
So not really sure what's going on and this might just be full on duct
tape, but it seems to work here. The machine has now survived a whole day
running that test whereas with superpage enabled it fails in less than
a minute usually.
TODO: might be nice to disable superpage only for the igfx iommu
instead of both iommus
TODO: would be nice to use the macros from include/drm/i915_pciids.h,
but can't do that with DECLARE_PCI_FIXUP_HEADER()

Broxton has known issues with VT-d superpage. Namely frame buffer
compression (FBC) can't be safely used when superpage is enabled.
Currently we're disabling FBC entirely when VT-d is active, but
I think just disabling superpage would be better since FBC can
save some power.

With the iommu driver disabling VT-d superpage it should be
safe to use FBC on SKL/BXT with VT-d otherwise enabled.

Sure. Unfortunately there's no convenient mechanism to do that in
