iio: adc: ad7380: fix adi,gain-milli property parsing

Browse Source 
Change the data type of the "adi,gain-milli" property from u32 to u16.
The devicetree binding specifies it as uint16, so we need to read it as
such to avoid an -EOVERFLOW error when parsing the property.

Fixes: c904e6dcf4 ("iio: adc: ad7380: add support for adaq4370-4 and adaq4380-4")
