[PATCH v2 0/6] Add BBML3 cpu feature

[Linu Cherian <linu.cherian@arm.com>]

- Patches 1, 2 and 3 adds more cpus to the bbml2_noabort 
  support list. bbml2_noabort would eventually gets renamed
  to bbml3 in a subsequent patch as they are functionally
  equivalent. 
- Patches 4, 5 & 6 introduces BBML3 cpu feature

Changelog from v1:
* Patches associated with adding cpus to BBML2_NOABORT,
  support list, were kept at bottom in v1 is now moved
  up in this version, for ease of backporting.

* Adding BBM_3 definition in sysreg moved into a separate patch

* MMFR2_ID check for BBM_3 has been changed from == BBM_3 to
  >= BBM_3, so that BBML3 cpu feature gets enabled for BBM_4 as well.

* For feature detection, MMFR2_ID check comes first followed by 
  midr check for code readability

* Errata details for C1-Ultra and C1-Premium added to commit message
