Peter Xu 651e4cefee intel_iommu: Add support for PCI MSI remap 
This patch enables interrupt remapping for PCI devices.

To play the trick, one memory region "iommu_ir" is added as child region
of the original iommu memory region, covering range 0xfeeXXXXX (which is
the address range for APIC). All the writes to this range will be taken
as MSI, and translation is carried out only when IR is enabled.

Idea suggested by Paolo Bonzini.
