gpu: nvgpu: force idle if railgate not supported
Add a way to force idle and reset the GPU in case where GPU
rail gating is not supported
(i.e. platform->can_railgate = false)
In this case, we follow below sequence :
- once GPU is idle, get runtime reference which enables the clocks
- call prepare_poweroff() to save the state explicitly
- perform explicit reset assert/deassert
- call finalize_poweron() to restore the state
- drop the runtime reference taken earlier
