drm/nouveau: Implement mmap as GEM object function

Browse source

Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.

The GEM object function is provided by GEM TTM helpers. Nouveau's
implementation of verify_access is unused and has been removed. Access
permissions are validated by the DRM helpers.

As a side effect, nouveau_ttm_vm_ops and nouveau_ttm_fault() are now
implemented in nouveau's GEM code.
