Tejal Kudav 87a8e8980a gpu: nvgpu: Correct dGPU shutdown path 
Currently, we just deinitialize the nvlink in the shutdown path.
This alone is not sufficient and can lead to someone trying to use
dGPU while being shutdown.
Avoid triggers to dGPU usage by -
1. Set NVGPU_DRIVER_IS_DYING to let users
know that the driver is currently in the process of dying.
2. Disable IRQs
3. Prepare for poweroff using nvgpu_prepare_poweroff
4. Stop CPU from accessing GPU registers
5. Set GPU state to POWEROFF
