Lars-Peter Clausen 8163663205 iio: Introduce iio_validate_scan_mask_onehot ...

Add a helper function for validating a scan mask for devices where exactly one
channel must be selected during sampling. This is a common case among devices
which have scan mask restrictions so it makes sense to provide this function in
the core.
