[PATCH v1 7/8] scsi: zorro7xx: Make use of struct zorro_device_id::driver_data_ptr

Usage of .driver_data_ptr allows to drop several casts. A nice upside of
that is that now the constness of the linked structures is kept and the
compiler warns about zdd missing a const. So add this missing const, too.

While touching the zorro_device_id array, drop an unneeded explicit zero
in the list terminator.
