[PATCH v1 10/17] thermal: Do not access 'type' field, use the tz id instead

The 'type' field is used as a name in the message. However we can have
multiple thermal zone with the same type. The information is not
accurate.

Moreover, the thermal zone device structure is directly accessed while
we want to improve the self-encapsulation of the code.

Replace the 'type' in the message by the thermal zone id.
