This all looks like it'd be a better candidate for runtime PM. The
implementation would be mostly the same, except that you'd need to
add a few more things to tegra_soctherm_probe() and use the runtime
PM API to enable/disable the device (clocks, resets, ...). System
sleep should then be taken care of automatically.
Another comment irrespective of that...

I wouldn't bother with the #ifdef, just always define the structure.
