[PATCH 2/5] iio: light: noa1305: Assign val in noa1305_measure()

[Marek Vasut <marex@xxxxxxx>]

Make noa1305_measure() behave similar to noa1305_scale(), make it
assign the 'val' output variable on success and return IIO_VAL_INT.
This further simplifies noa1305_read_raw() and allows removal of
ret variable altogether.
