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.
