[PATCH] hwmon: (tmp401) register with thermal subsystem

[PATCH] hwmon: (tmp401) register with thermal subsystem

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@free.fr>

tmp401 is missing HWMON_C_REGISTER_TZ. So a devicetree thermal
zone referencing a such sensor ('thermal-sensors = <&tmp411 N>')
fails to register it. Then its cooling-maps is not set, which means
that the fans are not managed.

Same as lm90 or jc42, set HWMON_C_REGISTER_TZ.
Boards without the property into the DT keep the same behavior.

It was checked on a LX2160A board that uses a TMP411 for the chassis ambient
input of a fan thermal zone.
Without this patch the zone silently never registers.
With this patch, the zone registers and the cooling-map drives the EMC2305
fans.
