Subject: [PATCH v2 04/16] thermal/hwmon: Do not set no_hwmon before calling thermal_add_hwmon_sysfs()

The thermal->tzp->no_hwmon parameter is only used when calling
thermal_zone_device_register().

Setting it to 'false' before calling thermal_add_hwmon_sysfs() has no
effect.

Remove the call and again prevent the drivers to access the thermal
internals.
