staging: comedi: dt282x: use comedi_fc helpers to validate timer args
Use the comedi_fc helper cfc_check_trigger_arg_is() to validate the
trigger arguments when the source is TRIG_TIMER.
All the arguments are unsigned int, change the local variable to an
unsigned int and rename it for aesthetic reasons.
