Konsta Holtta ed22056779 gpu: nvgpu: add disable_syncpoints debugfs node ...

To test semaphore-related bugs with igpus, add a debugfs node called
"disable_syncpoints" to override the "has_syncpoints" platform flag.
This makes job synchronization use semaphores, for example.

NVGPU_GPU_FLAGS_HAS_SYNCPOINTS is still reported in gpu characteristics
if the platform supports that, because it is filled in during boot.
