Subject: [PATCH] iio: adc: ti-ads124s08: Use gpiod_set_value_cansleep()

Using gpiod_set_value() to control the reset GPIO causes some verbose
warnings during boot when the reset GPIO is controlled by an I2C IO
expander.

As the caller can sleep, use the gpiod_set_value_cansleep() variant to
fix the issue.

Tested on a custom i.MX93 board with a ADS124S08 ADC.
