Deepak Nibade f28526bb72 gpu: nvgpu: move pmu_load_update() to get_dev_status() ...

We currently call gk20a_pmu_load_update() before calling
update_devfreq()

But it is possible to disable governor and set a
constant/max frequency.
In that case we will unnecessarily keep executing
gk20a_pmu_load_update() for each submit

Hence. move gk20a_pmu_load_update() to gk20a_scale_get_dev_status()
so that we call gk20a_pmu_load_update() only when we really
have to scale the frequency
