So that should be depends on THERMAL if THERMAL_OF

That's an inevitable consequence of adding this support, you can't get
around it.

This is still a hack; if this is causing real problems the thermal
subsystem should be doing something to avoid the issue (for example
providing an always built in stub) though I suspect in reality it's not
a practical issue.
