scsi: Drop gdth driver
The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which was manufactured by the now-defunct ICP Vortex company, later acquired by Adaptec and superseded by the aacraid series of controllers. The driver itself would require a major overhaul before any modifications can be attempted, but seeing that it's unlikely to have any users left it should rather be removed completely.
