staging: comedi: addi_apci_3xxx: remove COMEDI_SUBD_TTLIO

This driver abuses the enum comedi_subdevice_type by redefining
enum 11 - COMEDI_SUBD_SERIAL as COMEDI_SUBD_TTLIO. The subdevice
that uses COMEDI_SUBD_TTLIO is a TTL Digital Input/Output subdevice.

Remove COMEDI_SUBD_TTLIO and just use COMEDI_SUBD_DIO as the
subdevice type.
