Add support for creating/deleting ATA RAID's.

This completes the ATA RAID support, since all functions to manipulate
the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards
are only nessesary for booting.

I decided to allow for creation of ATA RAID's on any ATA controller, but
please keep in mind the restrictions on that. Due to the BIOS not
knowing what to do you can only boot from a RAID1 or the first disk
in a SPAN, if its not located on a "real" ATA RAID controller like
the Promise or Highpoint controllers.
