[POWERPC] ps3: repository misc fixes
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.
