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. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
