Thomas Fleury 525489f26e gpu: nvgpu: fix debugfs to disable big pages ...

After setting 'Y' in disable_bigpage, in native SMMU case,
we could still see 64K GMMU pages beeing used.

Fixed the following:
    - enforce disable_bigpage in nvgpu_vm_map
    - update GPU characteristics so that new clients know
      whether or not big pages are enabled. For instance
      this may affect how CUDA requests memory mapping.
