Subject: iio: adc: ad7173: fix setting ODR in probe

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.
