thermal: core: Change passive_delay and polling_delay data type 



It is better to use unsigned int as the data type for the passive_delay
and polling_delay arguments of thermal_zone_device_register_with_trips()
because they are implicitly cast to unsigned int anyway in
thermal_set_delay_jiffies() and if they happen to be negative at that
point, the resulting behavior may not be as desired.

Update the thermal_zone_device_register_with_trips() definition
accordingly.
