Most of the SPRS are the same as on POWER8, so we can re-use
the PowerISA 2.07 functions and simply amend the additional
registers afterwards.

v2:
- Removed GSR (SPR 158) since it is a write-only register
- Removed LMRR (813) and LMSER (814) since they have been removed
in PowerISA 3.0 B
- Added TIDR (144) which is a new register in PowerISA 3.0 B
BTW: In case somebody got some spare time and wants to increase
their patch count: Seems like TIDR (144) and PSSCR (823) are
currently not migrated right.
