drm/ttm: add drm_gem_ttm_mmap()
Add helper function to mmap ttm bo's using &drm_gem_object_funcs.mmap().
Note that with this code path access verification is done by
drm_gem_mmap() (which calls drm_vma_node_is_allowed(()).
The &ttm_bo_driver.verify_access() callback is is not used.
v3: use ttm_bo_mmap_obj instead of ttm_bo_mmap_vma_setup
