iommu/vt-d: Modify the format of intel DMAR tables dump

Presently, "/sys/kernel/debug/iommu/intel/dmar_translation_struct" file
dumps DMAR tables in the below format

IOMMU dmar2: Root Table Address:4362cc000
Root Table Entries:
 Bus: 0 H: 0 L: 4362f0001
 Context Table Entries for Bus: 0
  Entry	B:D.F	High	Low
  160   00:14.0	102     4362ef001
  184   00:17.0	302     435ec4001
  248   00:1f.0	202     436300001

This format has few short comings like
1. When extended for dumping scalable mode DMAR table it will quickly be
   very clumsy, making it unreadable.
2. It has information like the Bus number and Entry which are basically
   part of B:D.F, hence are a repetition and are not so useful.

So, change it to a new format which could be easily extended to dump
scalable mode DMAR table. The new format looks as below:

IOMMU dmar2: Root Table Address: 0x436f7d000
B.D.F	Root_entry				Context_entry
00:14.0	0x0000000000000000:0x0000000436fbd001	0x0000000000000102:0x0000000436fbc001
00:17.0	0x0000000000000000:0x0000000436fbd001	0x0000000000000302:0x0000000436af4001
00:1f.0	0x0000000000000000:0x0000000436fbd001	0x0000000000000202:0x0000000436fcd001
