The interrupt support for Advantech PCI-1730 currrently supports only rising edge inputs for the trigger sources. Each of four interrupt sources (each with its own Comedi subdevice) can be set to trigger on either a rising edge or a falling edge. Add support for choosing the edge during set-up of the asynchronous command for the subdevice, using the `CR_INVERT` bit of `scan_begin_arg` to indicate falling edge when set, or rising edge when clear. Also allow the `CR_EDGE` bit to be set, but ignore it. All other bits of `scan_begin_arg` must be zero.
