gpu: nvgpu: Remove unused function

Browse Source 
When compiling NVGPU with the GCC option '-Wmissing-prototypes' the
following error is observed ...

 nvgpu/drivers/gpu/nvgpu/os/linux/nvlink.c:42:5:
  error: no previous prototype for nvgpu_nvlink_train
  [-Werror=missing-prototypes]
   | int nvgpu_nvlink_train(struct gk20a *g, u32 link_id, bool from_off)
   |     ^~~~~~~~~~~~~~~~~~

The function nvgpu_nvlink_train() is no longer used and has not been
used for a long time. Therefore, fix the above by removing this legacy
function.
