Subject: iio: proximity: as3935: correct IIO_CHAN_INFO_RAW output

From: Matt Ranostay <mranostay@gmail.com>

commit 5138806f16c74c7cb8ac3e408a859c79eb7c9567 upstream.

IIO_CHAN_INFO_RAW was returning processed data which was incorrect.
This also adds the IIO_CHAN_INFO_SCALE value to convert to a processed value.
