Some of the TIMA Special CI operations perform the same operation at
alternative byte offsets and lengths.  The following
xive2_tm_opertions[] table entries are missing when they exist for
other offsets/sizes and have been added:
- lwz@0x810 Pull/Invalidate O/S Context to register    added
  lwz@0x818                                            exists
  ld @0x818                                            exists
- lwz@0x820 Pull Pool Context to register              added
  lwz@0x828                                            exists
  ld @0x828                                            exists
- lwz@0x830 Pull Thread Context to register            added
  lbz@0x838                                            exists
