zorro/UAPI: Use proper types (endianness/size) in <linux/zorro.h> 

Fix member definitions for non-native userspace handling:
  - All multi-byte values are big-endian, hence use __be*,
  - All pointers are 32-bit pointers under AmigaOS, but unused (except for
    cd_BoardAddr) under Linux, hence use __be32.
