iio: adc: ti-ads124s08: Use gpiod_set_value_cansleep() 

stable inclusion
from stable-v6.6.72
commit f110a6d71bd84a758a4c430dfffd5731091b3247
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBQN9L

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=f110a6d71bd84a758a4c430dfffd5731091b3247



--------------------------------

commit 2a8e34096ec70d73ebb6d9920688ea312700cbd9 upstream.

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.
