Remove dependency for nvgpu to invoke devfreq govenor on every
gk20a_busy/idle() call. This dependency was originally necessary to
track GPU load (busy vs idle) in software. However, since we currently
read the load GPU from HW/PMU there is no need to invoke the devfreq
governor in this path. Instead it can use timer-based polling.
