Suresh Siddha 1cb11583a6 x64, x2apic/intr-remap: disable DMA-remapping if Interrupt-remapping is detected (temporary quirk) 
Interrupt-remapping enables queued invalidation. And once queued invalidation
is enabled, IOTLB invalidation also needs to use the queued invalidation
mechanism and the register based IOTLB invalidation doesn't work.

For now, Support for IOTLB invalidation using queued invalidation is
missing. Meanwhile, disable DMA-remapping, if Interrupt-remapping
support is detected.

For the meanwhile, if someone wants to really enable DMA-remapping, they
can use nox2apic, which will disable interrupt-remapping and as such
doesn't enable queued invalidation.

And given that none of the release platforms support intr-remapping yet,
we should be ok for this temporary hack.
