Bring in IDE ATAPI floppy support.

Browse Source 
This is Junichi's v1.0 driver.

NOTE: Major device numbers have been changed to avoid conflict with other
      FreeBSD 3.0 devices.  The new numbers should be considered "official."
      This driver is still considered "beta" quality, although we have been
      playing with it.  Please submit bugs to junichi and myself.
