PATCH 1/1 libata atapi work #3

# This is a BitKeeper generated diff -Nru style patch. #
# ChangeSet
# 2004/05/13 21:26:59-04:00 [email protected]
# [libata] more ATAPI work - translate SCSI CDB to ATA PACKET
#

#   Now that we can specify ATAPI as a taskfile protocol, we can utilize
#   the existing SCSI->ATA translation infrastructure to build an ATA
#   PACKET command quickly and easily.
