[PATCH 06/11] thermal: Move get_tz_trend to the internal header

[Daniel Lezcano]

The function is not used in other place than the thermal directory. It
does not make sense to export its definition in the global header as
there is no use of it.

Move its the definition in the internal header and allow better
self-encapsulation.

Take the opportunity to add the parameter names to make checkpatch
happy and remove the pointless stubs.
