Sohil Mehta a6d268c619 iommu/vt-d: Add debugfs support for Interrupt remapping 
Debugfs extension for Intel IOMMU to dump Interrupt remapping table
entries for Interrupt remapping and Interrupt posting.

The file /sys/kernel/debug/iommu/intel/ir_translation_struct provides
detailed information, such as Index, Source Id, Destination Id, Vector
and the IRTE values for entries with the present bit set, in the format
shown.
