iio: adc: ad7173: fix setting ODR in probe
[ Upstream commit 6fa908abd19cc35c205f343b79c67ff38dbc9b76 ]
Fix the setting of the ODR register value in the probe function for
AD7177. The AD7177 chip has a different ODR value after reset than the
other chips (0x7 vs. 0x0) and 0 is a reserved value on that chip.
The driver already has this information available in odr_start_value
and uses it when checking valid values when writing to the
sampling_frequency attribute, but failed to set the correct initial
value in the probe function.
