[POWERPC] ps3: repository storage support 

Handle storage-related repository data:
  - Add missing implementations of ps3_repository_read_stor_*() repository
    accessors.
  - Dump storage properties in debug mode
  - Add PS3_DEV_TYPE_STOR_{DISK,ROM,FLASH} device types (which are identical to
    the corresponding SCSI device types) to enum ps3_dev_type
