libata: Add another column to the ata_timing table.
The forthcoming OCTEON SOC Compact Flash driver needs an additional timing value that was not available in the ata_timing table. I add a new column for dmack_hold time. The values were obtained from the Compact Flash specification Rev 4.1. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
