[PATCH 3/5] input: misc: AD714x: Fix thresh and completion interrupt mask and unmask functions

[<michael.hennerich@analog.com>]

From: Michael Hennerich <michael.hennerich@analog.com>

Fix two issues in the thresh and completion interrupt mask and unmask functions.
According to the AD714x datasheets the highest stage completion
interrupt should be enabled.
Fix mask computation.
