target-ppc: Implement "compat" CPU option
This adds basic support for the "compat" CPU option. By specifying
the compat property, the user can manually switch guest CPU mode from
"raw" to "architected".
This defines feature disable bits which are not used yet as, for example,
PowerISA 2.07 says if 2.06 mode is selected, the TM bit does not matter -
transactional memory (TM) will be disabled because 2.06 does not define
it at all. The same is true for VSX and 2.05 mode. So just setting a mode
must be ok.
This does not change the existing behavior as the actual compatibility
mode support is coming in next patches.
