thermal: thermal-core: Change temp type from unsigned to int 



Negative temperature values can be set by thermal clients
to the TSENS driver. Having unsgined long type prevents
clients using the set_trip_temp() thermal api to set
negative temperature values. On msm-3.4 kernel this api
had support to set negative temperature. Change the type
to support the negative temperature.
