William Breathitt Gray c3701185ee iio: dac: cio-dac: Fix max DAC write value check for 12-bit 
The CIO-DAC series of devices only supports DAC values up to 12-bit
rather than 16-bit. Trying to write a 16-bit value results in only the
lower 12 bits affecting the DAC output which is not what the user
expects. Instead, adjust the DAC write value check to reject values
larger than 12-bit so that they fail explicitly as invalid for the user.

Fixes: 3b8df5fd52 ("iio: Add IIO support for the Measurement Computing CIO-DAC family")
