Rodrigo Alencar 664b13498f iio: dac: ad5686: fix ref bit initialization for single-channel parts 
[ Upstream commit ecae2ae606 ]

The reference bit position was ignored when writing the register at the
probe() function (!!val was used). When such bit is 1, internal voltage
reference is disabled so that an external one can be used. For
multi-channel devices, bit 0 of the Internal Reference Setup command
behaves the same way, so AD5686_REF_BIT_MSK is created. The issue exists
since support for single-channel devices were first introduced.

Fixes: be1b24d245 ("iio:dac:ad5686: Add AD5691R/AD5692R/AD5693/AD5693R support")
