remove those and have a simple "nvkm_therm_clkgate_engine" function
This way you know that every user calls this function and don't have
to check for silly func...

[PATCH v2] drm/nouveau: Add support for clockgating on Fermi+
...5W.
Similar to how the nvidia driver seems to handle this, we enable
clockgating for each engine that supports it after it's initialization.
Changes since v1:
- Move function pointers for clockgating functions out of nvkm_therm,
just expose one less complex function to callers:
nvkm_therm_clkgate_engine()
- Use 0x44 for disabling clockgating instead of just shutting all of
nvidia's power management for each gate off, since that's what the
nvidia blob does
