Subject: [PATCH] iio: hid-sensor-prox: Restore lost scale assignments

The variables scale_pre_decml, scale_post_decml, and scale_precision were assigned in commit d68c592e02f6 ("iio: hid-sensor-prox: Fix scale not correct issue"), but due to a merge conflict in
commit 9c15db92a8e5 ("Merge tag 'iio-for-5.13a' of
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next"), these assignments were lost.

Add back lost assignments and replace st->prox_attr with st->prox_attr[0] because commit 596ef5cf654b ("iio: hid-sensor-prox: Add support for more channels") changed prox_attr to an array.
