Subject: hwmon: (adt7411) set bit 3 in CFG1 register

From: Michael Walle <[email protected]>

commit b53893aae441a034bf4dbbad42fe218561d7d81f upstream.

According to the datasheet you should only write 1 to this bit. If it is not set, at least AIN3 will return bad values on newer silicon revisions.
