If we cannot setup rc6, we cannot let the GPU suspend itself as it
cannot save its state (to a powercontext). As such, we must disable
runtime-pm, but we should do so using the low-level pm-runtime function
which leaves our own debugging functions intact (and continue to detect
errors in our runtime-pm handling should we ever be able to enable rc6).
