staging: comedi: amplc_dio200_common: correct bound on counter mode
For the mode configured by the `INSN_CONFIG_SET_COUNTER_MODE` comedi
instruction for the counter subdevice channels supported by this module,
the upper bound should be `I8254_MODE5 | I8254_BCD` ((5 << 1) | 1)
rather than `I8254_MODE5 | I8254_BINARY` ((5 << 1) | 0). Fix it.
