[PATCH 11/11] thermal: Move thermal governor structure to internal header

[Daniel Lezcano]

The thermal governor structure is a big structure where no
user should change value inside except via helper functions.

Move the structure to the internal header thus preventing external
code to be tempted by hacking the structure's variables.
