iommu/vt-d: Add debugfs support to show context internals
Export Intel IOMMU DMA remapping internal states, such as root and
context table entries in debugfs.
Example of such dump in Kabylake:
/sys/kernel/debug/iommu/intel/dmar_translation_struct
IOMMU dmar0: Root Table Address:45699c000
Root Table Entries:
Bus: 0 H: 0 L: 45699f001
Context Table Entries for Bus: 0
Entry B:D.F High Low
16 00:02.0 102 45699e005
IOMMU dmar1: Root Table Address:45699d000
Root Table Entries:
Bus: 0 H: 0 L: 45644f001
Context Table Entries for Bus: 0
Entry B:D.F High Low
160 00:14.0 102 45644e001
