Various fixes for the PS3 repository code:
- Sync signatures of function prototypes and implementations (enum vs.
unsigned int)
- Correct references to `regions' as `registers':
o Correct enum ps3_region_type as enum ps3_reg_type,
o Correct PS3_REGION_TYPE_* as PS3_REG_TYPE_*,
o Correct ps3_repository_find_region() as ps3_repository_find_reg().
- Correct function name in pr_debug() call
- Minor error condition improvements.
