[PATCH] iio/axp288_adc: add missing channel info mask

[Jacob Pan <jacob.jun.pan@linux.intel.com>]

Commit 65de7654d39c70c2b ("iio: iio: Fix iio_channel_read return if
channel havn't info") added a check for valid info masks.

This patch adds missing channel info masks for all ADC channels.
Otherwise, iio_read_channel_raw() would return -EINVAL when called
by consumer drivers.
