s->maxdata for the do subdevice should be 1, however currently it is
being set to 0xffffffff. Fix this.

This patch is at the end because I'm somewhat uncertain of its
correctness. Every other addi_apci_* driver with a digital output
subdevice sets s->maxdata to 1 so I'd be surprised if just this board
differed, but I'm not familiar enough with the hardware to verify that
myself. I'd appreciate a verification that this is a correct change.
Thanks!
