Konsta Holtta afe12a49f7 gpu: nvgpu: add missing busy calls for ctrl ioctls ...

The following ioctls:

- NVGPU_GPU_IOCTL_WAIT_FOR_PAUSE
- NVGPU_GPU_IOCTL_RESUME_FROM_PAUSE
- NVGPU_GPU_IOCTL_TRIGGER_SUSPEND
- NVGPU_GPU_IOCTL_CLEAR_SM_ERRORS

access hardware registers, so they should make sure that the gpu is
powered on first. Add gk20a_{busy,idle}() pairs for them.
