3.16.7-ckt9 -stable review patch. If anyone has any objections, please let me know.

From: Stefan Wahren <stefan.wahren@i2se.com>
commit 03305e535cd5cdc1079b32909bf4b2dd67d46f7f upstream.
Since commit c8231a9af8147f8a ("iio: mxs-lradc: compute temperature from channel 8 and 9") with the removal of adc channel 9 there is no 1-1 mapping in the channel spec.
All hwmon channel values above 9 are accessible via there index minus one. So add a hidden iio channel 9 to fix this issue.
