The value of the GPIOs is currently altered using offsets rather
than masks. Make use of __assign_bit and the BIT macro to turn
the offsets into masks.

Fixes: fea251b6a5db ("iio: addac: add AD74413R driver")
Signed-off-by: Cosmin Tanislav <cosmin.tanislav@analog.com>
---
V1 -> V2
 * add Fixes tag
 * use __assign_bit
 * remove bitmap_zero

V2 -> V3
 * add back line between real_offset declaration and __assign_bit call
 * move before patch 2
