gpu: nvgpu: IOCTL to disable timeouts
Add IOCTL NVGPU_DBG_GPU_IOCTL_TIMEOUT to support
disabling/re-enabling scheduler timeout from user space
If user space application is closed without re-enabling
the timeouts, kernel will restore the timeouts' state
while releasing the debug session
This is needed for debugging purpose
