[PATCH v2 2/7] thermal/core: Encapsulate tz->device field

[Daniel Lezcano <daniel.lezcano@linaro.org>]

There are still some drivers needing to play with the thermal zone
device internals. That is not the best but until we can figure out if
the information is really needed, let's encapsulate the field used in
the thermal zone device structure, so we can move forward relocating
the thermal zone device structure definition in the thermal framework
private headers.
