sd: add support for TCG OPAL self encrypting disks
Just wire up the generic TCG OPAL infrastructure to the SCSI disk driver and the Security In/Out commands. Note that I don't know of any actual SCSI disks that do support TCG OPAL, but this is required to support ATA disks through libata. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Martin K.
