Add support for issuing ATA_16 passthru commands to ATAPI devices
managed by libata.  It requires the previous CDB length fix patch.

A boot/module parameter, "atapi_scmd85=1" can be used to globally
disable this feature, if ever desired.

tj: renamed ata16_passthru module param to atapi_passthru16 and invert
    its meaning to reduce confusion.

tj: restructured __ata_scsi_queuecmd() according to Jeff's suggestion.

Alright, the winner is atapi_passthru16.
