Use the comedi_subdevice 'readback' member and the core provided (*insn_read)
to handle the readback of the write-only analog output subdevice. Remove the
then unused 'ao_data' member from the private data.
The private data is now unnecessary. Remove it and the allocation.

This function is only called by the (*auto_attach) to reset all the analog
output channels. For aesthetics, absorb the function.
Fix the range programming for each channel. According to the users manual
the "range strobe" register needs to be written after setting the "DAC range
control" register in order to load the range setting.

The pci1723_reset() function simply resets all the analog output channels
to 0V and a +/-10V range. This really isn't necessary when detaching the
driver.
Remove the board reset and just use comedi_pci_detach() directly for the
(*detach).

Most of the comedi drivers that provide readback for write only subdevices now
use the comedi core comedi_alloc_subdev_readback() helper to allocate the subdevice
'reaback' member instead of using some member in their private data. These drivers
also hook up the (*insn_read) callback to the comedi_readback_insn_read() helper to
provide the readback.
Have the core automatically hook up the (*insn_read) callback after allocating the
memory if the driver has not already hooked it up to a private function.
