[SCSI] remove m68k NCR53C9x based drivers

These drivers depend on the deprecated NCR53C9X core and need to be converted
to the esp_scsi core.

-/* The Blizzard 1230 DMA interface
- * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- * Only two things can be programmed in the Blizzard DMA:
- *  1) The data direction is controlled by the status of bit 31 (1 = write)
- *  2) The source/dest address (word aligned, shifted one right) in bits 30-0
- *
- * Program DMA by first latching the highest byte of the address/direction
- * (i.e. bits 31-24 of the long word constructed as described in steps 1+2
- * above). Then write each byte of the address/direction (starting with the
- * top byte, working down) to the DMA address register.
- *
- * Figure out interrupt status by reading the ESP status byte.
