thermal: streamline get_trend callbacks
The .get_trend callback in struct thermal_zone_device_ops has the prototype: int (*get_trend) (struct thermal_zone_device *, int, enum thermal_trend *); whereas the .get_trend callback in struct thermal_zone_of_device_ops has: int (*get_trend)(void *, long *); Streamline both prototypes and add the trip argument to the OF callback aswell and use enum thermal_trend * instead of an integer pointer. While the OF prototype may be the better one, this should be decided at framework level and not on OF level.
