[libata] mark certain hardware (or drivers) with a no-atapi flag
Some hardware does not support the PACKET command at all.
Other hardware supports ATAPI, but the driver does something nasty such
as calling BUG() when an ATAPI command is issued.
For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI.
Initial version contributed by Ben Collins.
