Sample values in comedi are generally represented as unsigned values. Use unsigned types for sample value manipulations in the "rtd520" driver for consistency. Also replace the hand-coded munging of 2's complement sample values with calls to `comedi_offset_munge()` and AND with `s->maxdata` to strip off any extra sign bits. Signed-off-by:
