please move this patch at the beggining of the patch series so it can be
applied immediately (patch #2 needs some more work)

Please also note that patch #2 moved these defines to ide-floppy.h and now
patch #3 removes them so by re-ordering patches you can make patch #2 simpler.

[ This is a general hint for optimizing patches to make them smaller and easier
  to maintain, it also makes reviewer's job easier. ]

0xaa is a generic SCSI opcode so the above comment is not necessary
