From: Guenter Roeck <linux@roeck-us.net>

[ Upstream commit 9de15c95a63f527c8f7a968cd95e6ec71fc6891d ]

Similar to other recent chips from Nuvoton, IO mapping may be disabled
by default. Enable it when instantiating the driver and after resume.

Fixes: 0599682b826f ("hwmon: (nct6775) Add support for NCT6798D")
Fixes: e41da286a2fd ("hwmon: (nct6775) Add support for NCT6797D")
