4.20-stable review patch. If anyone has any objections, please let me know.
------------------
[ 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: e41da286a2fd ("hwmon: (nct6775) Add support for NCT6797D")
