mambo: Update P9 PVR to reflect Scale out 24 core chips
The P9 PVR bits 48:51 don't indicate a revision but instead different
configurations. From BookIV we have:
Bits: Configuration
0: Scale out 12 cores
1: Scale out 24 cores
2: Scale up 12 cores
3: Scale up 24 cores
Skiboot will mostly the use "Scale out 24 core" configuration
(ie. SMT4 not SMT8) so reflect this in mambo.
