Subject: [PATCH v2 1/4] iio: backend: update iio_backend_oversampling_ratio_set

In the function iio_backend_oversampling_ratio_set the chan parameter
was added. The function can be used in contexts where the channel
must be specified. All affected files have been modified.

changes in v2:
 - remove iio_backend_set_dec_rate function and use 
   iio_backend_oversampling_ratio_set function
