Subject: [PATCH 07/13] thermal: of: streamline .get_temp callbacks

In the thermal framework it was decided that temperatures can't
be negative, so let the .get_temp callback in struct
thermal_zone_of_device_ops take an unsigned long pointer for
the temperature like the .get_temp callback in
struct thermal_zone_device_ops does.
