ide-floppy updates: 

o byte -> u8
o remove various status register definitions, these are now ata (atapi)
  generic
o ide-iops changes
o remove idefloppy_end_request(), dupe of ide core helper
o driver->end_request changes
o lots of style cleanups
o update to new dma interface
o ->reinit to ->attach updates
