iommu/vt-d: Call dmar_can_force_on() for tboot opt-in

Browse source

So the policy of requesting ACS in detect_intel_iommu() is consistent
with that in tboot_force_iommu().

Though tboot is the strongest override so far, dmar_can_force_on() may
return false due to future extensions. In this case panic the kernel,
as is already done when failing to initialize DMA remapping for tboot.

No functional impact at this point.
