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Adaptec and superseded by the aacraid series of controllers.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.

-/* All GDT Disk Array Controllers are fully supported by this driver.
- * This includes the PCI SCSI Disk Array Controllers and the

- * 
- * After the optional list of IRQ values, other possible 
- * command line options are:
- * disable:Y                    disable driver
- * disable:N                    enable driver
- * reserve_mode:0               reserve no drives for the raw service
- * reserve_mode:1               reserve all not init., removable drives
- * reserve_mode:2               reserve all not init. drives
- * reserve_list:h,b,t,l,h,b,t,l,...     reserve particular drive(s) with 
- *                              h- controller no., b- channel no., 
- *                              t- target ID, l- LUN
- * reverse_scan:Y               reverse scan order for PCI controllers         
- * reverse_scan:N               scan PCI controllers like BIOS
- * max_ids:x                    x - target ID count per channel (1..MAXID)
- * rescan:Y                     rescan all channels/IDs 
- * rescan:N                     use all devices found until now
- * hdr_channel:x                x - number of virtual bus for host drives
- * shared_access:Y              disable driver reserve/release protocol to 
- *                              access a shared resource from several nodes, 
- *                              appropriate controller firmware required
- * shared_access:N              enable driver reserve/release protocol
- * force_dma32:Y                use only 32 bit DMA mode
- * force_dma32:N                use 64 bit DMA mode, if supported
- *
- * The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N,

- * Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y".
- * 
- * When loading the gdth driver as a module, the same options are available. 
- * You can set the IRQs with "IRQ=...". However, the syntax to specify the
- * options changes slightly. You must replace all ',' between options 
- * with ' ' and all ':' with '=' and you must use 
- * '1' in place of 'Y' and '0' in place of 'N'.
- * 
- * Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0
- *           max_ids=127 rescan=0 hdr_channel=0 shared_access=0
