Divya Singhatwaria 7ff977063b gpu: nvgpu: add elpg protection for tpc_enabled_exceptions ...

- DeviceGetTpcExceptionEnMask test calls ioctl
  NVGPU_GPU_IOCTL_GET_TPC_EXCEPTION_EN_STATUS which reads
  register gr_gpc0_tpc0_tpccs_tpc_exception_en_r(). This causes
  IDLE_SNAP and further disengages ELPG.
- Add elpg protected call for the tpc_enabled_exceptions HAL.
