Wilfried Wessner 4458ae8d40 iio: adc: ad7949: fix wrong ADC result due to incorrect bit mask 
commit f890987fac8153227258121740a9609668c427f3 upstream.

Fixes a wrong bit mask used for the ADC's result, which was caused by an
improper usage of the GENMASK() macro. The bits higher than ADC's
resolution are undefined and if not masked out correctly, a wrong result
can be given. The GENMASK() macro indexing is zero based, so the mask has
to go from [resolution - 1 , 0].

Fixes: 7f40e0614317f ("iio:adc:ad7949: Add AD7949 ADC driver family")
