[PATCH v2 00/27] target/ppc: SPR registration cleanups

[Fabiano Rosas]

The goal of this series is to do some untangling of SPR registration
code in cpu_init.c and prepare for moving the CPU initialization into
separate files for each CPU family.

After this series we'll have only cpu-specific SPR code in cpu_init.c,
i.e. code that can be split and moved as a unit into other
files. Common/generic SPR code will be in helper_regs.c, exposed via
spr_common.h.

Changes from v1:

- Some commit message improvements suggested by David;

- Removed the soft_tlb rename patch. Kept the old name;

- Left the specific check_pow functions behind, they can be dealt with
  in the next series;

- Added a new patch to rename spr_tcg to spr_common.

Patches 23 and 26 still need review.

This series is based on legoater/ppc7.0.
