iio: common: st_sensors: check odr address value in st_sensors_set_odr()
Do not try to configure sample frequency if the sensor do not export odr register address in register map. That change will be used to properly support LIS3DHH accel sensor. Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@st.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
