056401eae6 PowerPC 601 need specific callbacks for its BATs setup.
Implement PowerPC 601 HID0 register, needed for little-endian mode support.
As a consequence, we need to merge hflags coming from MSR with other ones.
Use little-endian mode from hflags instead of MSR during code translation.

faadf50e29 PowerPC MMU and exception fixes:
* PowerPC 601 (and probably POWER/POWER2) uses a different BAT format than
  later PowerPC implementation.
* Bugfix in BATs check: must not stop after 4 BATs when more are provided.
* Enable POWER 'rac' instruction.
* Fix exception prefix for all supported PowerPC implementations.
* Fix exceptions, MMU model and bus model for PowerPC 601 & 620.
* Enable PowerPC 620 as it could mostly boot a PreP target.

6ebbf39000 Replace is_user variable with mmu_idx in softmmu core,
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
