iio: adc: ad7124: Benefit of dev = indio_dev->dev.parent in ad7124_parse_channel_config()

Since commit a6eaf02b8274 ("iio: adc: ad7124: Switch from of specific to
fwnode based property handling") the function
ad7124_parse_channel_config() has a parameter `dev` that holds
the value `indio_dev->dev.parent`. Make use of that to shorten two code
lines.
