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.
