This makes INSN_CONFIG_DIO_{INPUT,OUTPUT,OPENDRAIN} simply be copies of the
already-existing constants COMEDI_INPUT, COMEDI_OUTPUT, and
COMEDI_OPENDRAIN.
This change also ensures that if a user happens to use, for example,
COMEDI_INPUT in place of where INSN_CONFIG_DIO_INPUT, the result will
always be the same and also acceptable and correct usage.
