v1-> v2:
- Collected the tags (Thanks to Christophe Leroy)
- Rename skip to optional and check optional while printing
  (Christophe Leroy)
- Decided not to add cpu_has_feature(CPU_FTR_DBELL) while printing.
  This feature is mostly true for majority of platforms and adding check
  means more ifdefs in that path. Prinitng "Doorbell interrupts" shouldn't
  cause any issue when feature if off since all entries would be zero.

This series is based on work by Thomas Gleixner[1].
Further details can be found in cover-letter of v1.
