More PowerPC definitions, from POWER 2.04 specifications and misc sources.
Check that at least instructions set and SPRs are correct for
PowerPC 401, 403, 405 and 440 cores.
Implement PowerPC 401 MMU model (real-mode only).
Improve INSNs and SPRs dump to ease parse with standard shell tools.
Add more precise status for most PowerPC cores families.
