Subject: [PATCH 5/8] thermal/drivers/int3400: Use thermal zone device wrappers

The driver is accessing the thermal zone device structure but the
accessors are already existing and we want to consolidate the thermal
core code by preventing accesses to the internals from the drivers.

Let's use these accessors.

On the other side, the code is getting directly the temperature from
tz->temperature, but the temperature is a faked on, so we can replace
this access by the fake temp and remove the thermal zone device
structure access.
