[SCSI] remove m68k NCR53C9x based drivers

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

-/* TODO:
- *
- * o According to the doc from laire, it is required to reset the DMA when
- *   the transfer is done. ATM we reset DMA just before every new 
- *   dma_init_(read|write).
- *
- * 1) Figure out how to make a cleaner merge with the sparc driver with regard
- *    to the caches and the Sparc MMU mapping.
- * 2) Make as few routines required outside the generic driver. A lot of the
- *    routines in this file used to be inline!
