Joshua DeWeese 86d751d4d3 sys/analog_util/dac_util: fix truncation bug ...

In `dac_util_map(...)` the expression `((value - min) * UINT16_MAX)` was
cast to a 16 bit unsigned, then divided by `(max - min)`. This means
that anytime `(value - min) != 0` the numerator was truncated prior to
being divided and then returned.

This patch modifies the expression so that the downcast to 16 bits is
performed as the last operation.
