This driver requires an IRQ and 2 DMA channels in order to execute async

staging: comedi: dt282x: fix dt282x_ao_insn_write()
The (*insn_write) functions are expected to write 'insn->n' samples to the
hardware. Fix this function so it works like the comedi core expects.
The comedi core sanity checks that the samples are within the 'maxdata' range
of the subdevice before calling the (*insn_write) so this function does not
need to mask each sample by 's->maxdata'.
Also, the wrong '*2scomp' flag in the private data was being checked to see
if the sample needs to be munged before being written. Fix this.

staging: comedi: dt282x: convert 'dabits' boardinfo to 'ao_maxdata'
This member of the boardinfo is the number of bits in the analog output data.
Convert this member into the subdevice 'maxdata', (1 << board->dabits) - 1,
to avoid needing to do the calculation.
Use the subdevice 'maxdata' in the driver instead of using the boardinfo and
use the comedi_offset_munge() helper to convert the two's complement data to
the offset binary form that the comedi core expects.
